Chapter 14, Problem 93SCQ

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

H₂(g) + I₂(g) → 2 HI(g)    Rate = k[H₂][I₂]

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

1. (a) The reaction must occur in a single step.
2. (b) This is a second-order reaction overall.
3. (c) Raising the temperature will cause the value of k to decrease.
4. (d) Raising the temperature lowers the activation energy for this reaction.
5. (e) If the concentrations of both reactants are doubled, the rate will double.
6. (f) Adding a catalyst in the reaction will cause the initial rate to increase.
