Chapter 13 Homework

1. You perform some experiments for the reaction A>B +C and determine the rate law has the form.

Rate=k[A]*

Calculate the value of exponent x for each of the following.

a. [A] is tripled and you observe no rate change

b. [A] is doubled and the rates doubles

c. [A] is tripled and the rate goes up by the factor of 27

2. Sulfuryl chloride, SO2 Cl2, decomposes when heated.

SO2Cl2 (g) > SO2 (g) + Cl2 (g)

In an experiment, the initial concentration of SO2Cl2 was 3.00 x 10^-2 mol/L. If the rate constant is 2.2 x 10^-5 /s, what is the concentration of SO2Cl2 after 6.0 hr? The reaction is first order.

Concentration= mol/L

3. The rate of a particular reaction doubles when the temperature is increased from 25°C to 35°C. Calculate the activation energy for this reaction.
