Reaction Rates and Equilibrium

Reaction Rates and Equilibrium. What is meant by the rate of a chemical reaction?. Can also be explained as the speed of he reaction, it is the amount of time required for a chemical reaction to come to completion. Different reactions take different times Burning Aging Ripening Rusting.

Second-Order Processes

Second-Order Processes. Graphing ln 1/[NO 2 ] vs. t , however, gives this plot. Because this is a straight line, the process is second-order in [A]. Half-Life. Half-life is defined as the time required for one-half of a reactant to react.

Reaction Mechanisms

Reaction Mechanisms. Chapter 14. Reaction Mechanisms. The sequence of events that describes the actual process by which reactants become products is called the reaction mechanism. Reaction Mechanisms. Reactions may occur all at once or through several discrete steps.

Termolecular

Termolecular. Fast Initial Step. 2 NO ( g ) + Br 2 ( g ) ??? 2 NOBr ( g ). The rate law for this reaction is found to be Rate = k [NO] 2 [Br 2 ] Because termolecular processes are rare, this rate law suggests a two-step mechanism. Step 1: NO + Br 2. NOBr 2 (fast).
