The decomposition of Br2 was followed as a function of
Chapter 13, Problem 6SAQ(choose chapter or problem)
The decomposition of \(Br_2\) was followed as a function of time; two different plots of the data are shown here. Determine the order and rate constant for the reaction.
a) first order; \(0.030 \mathrm{~s}^{-1}\)
b) first order; \(33.3 \mathrm{~s}^{-1}\)
c) second order; \(0.045 \mathrm{M}^{-1} \cdot \mathrm{s}^{-1}\)
d) second order; \(22.2 \mathrm{M}^{-1} \cdot \mathrm{s}^{-1}\)

ANSWER:
Step 1 of 2
The rate of reaction is dependent on the concentration of the reactants by the rate law.
![Rate = k[A]^{n}](https://lh6.googleusercontent.com/9z7UBERQsHjpzNWbdBfv18C78fRg-4cewVY93woqHCXr4w2j26_sk-BcIqP8LaS3t_7MZbAn3RMA4MqVJtjBHvAi5TSuq1EP1CyssHp9kd0sZ1wzTH8t56-b8rLXSV-UnVln6dg5Y-0tJNuz6coE5w)
K = Proportionality constant
- concentration of the reactant

n = order of the reaction.
From the plot of the graph depicting the decomposition of bromine is linear where the straight line fits the data points, the reaction is the first order.
