Explanation:
Hello!
13. In this case, according to the units, we infer this is a second-order reaction which has the following integrated rate law:
Which can be solved for the time as shown below:
Thus, we plug in the given concentrations and rate constant to obtain:
For the second part, we proceed by using the same rate constant and the new initial concentration as follows:
14. In this case, according to the units of the rate constant, we infer this is a zeroth-order reaction, therefore we compute the half-life has shown below:
Thus, we plug in to obtain:
Best regards!
