Question

Kindly answer question c

(a). Consider the reaction A2(g) + B2(g)
2 AB(g). The reaction of a fixed
amount of A2 and B2 is studied in a cylinder fitted with a movable piston.
Indicate the effect of each of the following changes on the rate of reaction:
(i). an increase in temperature at constant volume.
(ii). an increase in volume at constant temperature.
(iii). addition of a catalyst.
(b). Decomposition of N2O5 is a first order reaction. At 25 °C, it takes 6.2 hours for
the concentration to drop from 0.130 to 0.065 M. Calculate the time it takes for
the concentration to drop from 0.480 to 0.015 M.
(c). In the laboratory, you wish to determine the reaction order and rate constant
for the following thermal decomposition reaction:
2 AB2
A2 + 2 B2
(i).
Identify the data you will collect.
(ii). Explain how you would use these data to determine whether the reaction
is zero order, first order or second order and the value of the rate
constant.
