Reaction Concentration and Time for 1st Order Reactions (2)
How does one use this equation? Consider knowing the concentration [A] at time zero, [A0] and the rate constant, k, and being asked for the concentration [A] at some other time. Let’s say that [A0] = 1.234 moles/liter, and k = 0.0012 sec-1. What is the amount of A, i.e. [A] at time = 31.4 seconds?
