Question

The reaction between A and B has the rate law Rate = k[A][B]. A reaction is conducted with [A]0 = 0.0245 M and [B]0 = 3.24 × 10–5 M, and the natural logarithm of the concentration of [B] is plotted as a function of time in seconds. The plot is linear, with a slope of –3.96 × 10–4. What is the value of k?

A.

3.96 × 10–4 M–1 s–1

B.

1.62 × 10–2 M–1 s–1

✓ Correct
C.

12.2 M–1 s–1

D.

499 M–1 s–1
