  39. $400 Answer from C4 What is by adding coefficients? Back to Jeopardy

  40. $500 Question from C4 Description of how concentration and temperature are related to the rate of a chemical reaction. Then identify and describe one more factor that can affect reaction rate.

  41. $500 Answer from C4 What is: Concentration describes the number of particles in a given volume. As the concentration of the reactants increases, there are more particles to collide and react with one another. This can increase the reaction rate. Temperature is related to the rate of a reaction. Temperature is also related to energy, when you add energy to a reaction, it increases particle motion. This increase in motion is measured by an increase in temperature. Reactions at higher temperatures have reactant particles that are moving faster. This results in more reactant collisions and a faster reaction rate. Increased surface area means that more of the surface of the reactant is exposed. As surface area increases, the rate of reaction increases. Back to Jeopardy
