What is the rate constant for the destruction of a substance if it is a first-order reaction, the rate of production of a substance is 1.0 x 10-10 mole/L hr, and the concentration is 0.2 x 10-8 mole/L. The rate law for the destruction is given as -∆[X] /∆t. Assume that the rate of destruction is equal to the rate of production.
A. 1.39 x 10-5 day-1
B. 1.39 x 10-5 hr-1
C. 1.39 x 10-5 min-1
D. 1.39 x 10-5 sec-1
