  1. Temperature and Keq Lesson # 11

  2. How Does Temperature Change the Keq? The Keq is a mathematical constant that does not change for concentration, volume, and pressure changes. It only changes for temperature. 1. Exothermic Reactions: A + B ⇋ C + energy

  3. How Does Temperature Change the Keq? The Keq is a mathematical constant that does not change for concentration, volume, and pressure changes. It only changes for temperature. 1. Exothermic Reactions: A + B ⇋ C + energy Increasing the temperature causes the Keq to

  4. How Does Temperature Change the Keq? The Keq is a mathematical constant that does not change for concentration, volume, and pressure changes. It only changes for temperature. 1. Exothermic Reactions: A + B ⇋ C + energy Increasing the temperature causes the Keq to decrease. Decreasing the temperature causes the Keq to

  5. How Does Temperature Change the Keq? The Keq is a mathematical constant that does not change for concentration, volume, and pressure changes. It only changes for temperature. 1. Exothermic Reactions: A + B ⇋ C + energy Increasing the temperature causes the Keq to decrease. Decreasing the temperature causes the Keq to increase. Increasing [A] causes the reaction to shift

  6. How Does Temperature Change the Keq? The Keq is a mathematical constant that does not change for concentration, volume, and pressure changes. It only changes for temperature. 1. Exothermic Reactions: A + B ⇋ C + energy Increasing the temperature causes the Keq to decrease. Decreasing the temperature causes the Keq to increase. Increasing [A] causes the reaction to shift right and the value of the Keq to

  7. How Does Temperature Change the Keq? The Keq is a mathematical constant that does not change for concentration, volume, and pressure changes. It only changes for temperature. 1. Exothermic Reactions: A + B ⇋ C + energy Increasing the temperature causes the Keq to decrease. Decreasing the temperature causes the Keq to increase. Increasing [A] causes the reaction to shift right and the value of the Keq to remain constant.

  8. How Does Temperature Change the Keq? The Keq is a mathematical constant that does not change for concentration, volume, and pressure changes. It only changes for temperature. 2. Endothermic Reactions: A + B + energy⇋ C

  9. How Does Temperature Change the Keq? The Keq is a mathematical constant that does not change for concentration, volume, and pressure changes. It only changes for temperature. 2. Endothermic Reactions: A + B + energy⇋ C Decreasing the temperature causes the Keq to

Endothermic Reactions: A + B + energy⇋ C Decreasing the temperature causes the Keq to decrease. Increasing the temperature causes the Keq to

  11. How Does Temperature Change the Keq? The Keq is a mathematical constant that does not change for concentration, volume, and pressure changes. It only changes for temperature. 2. Endothermic Reactions: A + B + energy⇋ C Decreasing the temperature causes the Keq to decrease. Increasing the temperature causes the Keq to increase. Decreasing [A] causes the reaction to shift

  12. How Does Temperature Change the Keq? The Keq is a mathematical constant that does not change for concentration, volume, and pressure changes. It only changes for temperature. 2. Endothermic Reactions: A + B + energy⇋ C Decreasing the temperature causes the Keq to decrease. Increasing the temperature causes the Keq to increase. Decreasing [A] causes the reaction to shift left and the value of the Keq to

  13. How Does Temperature Change the Keq? The Keq is a mathematical constant that does not change for concentration, volume, and pressure changes. It only changes for temperature. 2. Endothermic Reactions: A + B + energy⇋ C Decreasing the temperature causes the Keq to decrease. Increasing the temperature causes the Keq to increase. Decreasing [A] causes the reaction to shift left and the value of the Keq to remain constant.

  14. 3. PBr3(g) + Br2(g)⇋ PBr5(g) @ 100 oC Keq = 0.17 & @ 200 oC Keq = 0.091 Is the reaction endothermic or exothermic?

  15. 3. PBr3(g) + Br2(g)⇋ PBr5(g) @ 100 oC Keq = 0.17 & @ 200 oC Keq = 0.091 Is the reaction endothermic or exothermic? The temperature was increased and the Keq decreased or it shifted left.

  16. 3. PBr3(g) + Br2(g)⇋ PBr5(g) + energy @ 100 oC Keq = 0.17 & @ 200 oC Keq = 0.091 Is the reaction endothermic or exothermic? The temperature was increased and the Keq decreased or it shifted left. Exothermic reactions shift left when heated.
