First-Order Reaction Rate Calculation

Medium General Chemistry Chemical Kinetics

A reaction between reactant A and reactant B follows first-order kinetics with respect to each reactant. The rate constant for the reaction is k = 2.5 × 10^-3 s^-1. If the initial concentrations of both A and B are 0.10 M, what is the rate of the reaction after 30 seconds?

1.5 × 10-4 M/s
