Question

Determine the rate constant using data from the first column?

Answer 1

To determine the rate constant (k), use the integrated rate law corresponding to the determined reaction order and the data from the first trial that provides concentration and rate.

Step-by-step explanation:

To determine the rate constant (k) using data from the first column, we would apply the integrated rate law corresponding to the reaction order, which can be found from experimental data. If the reaction is first order, the rate law is rate = k[A] and for a second-order reaction, the rate law is rate = k[A]². For example:

• If the experimentally determined rate law is rate = k[A] and using data from the first trial, where the dataset provides the concentration of A and the corresponding rate, you can solve for k by rearranging the formula to k = rate / [A].
• If the reaction is second order with respect to A, and the rate law is rate = k[A]², you would solve for k by rearranging the formula to k = rate / [A]².

For example, if it is known that the reaction is first order and using data from Experiment 1 where the rate is 1.60 × 10-8 M/s and the concentration of A is 0.010 M, you would solve for the rate constant as follows:

1.60 × 10-8 M/s = k(0.010 M)

Solving for k gives:

1.6 × 10-6 s-1 = k
