Chapter 11, Problem 11.98PAE

The following statements relate to the reaction for the formation of HI:

H₂(g) + I₂(g) -* 2 HI(g) Rate = it[HJ [I₂J

Determine which of the following statements are true. If a statement is false, indicate why it is incorrect.

1. The reaction must occur in a single step.

This is a second-order reaction overall.

Raising the temperature will cause the value of k to decrease.

Raising the temperature lowers the activation energy' for this reaction.

If the concentrations of both reactants are doubled, the rate will double.

Adding a catalyst in the reaction will cause the initial rate to increase.
