WebJun 9, 2015 · To find the initial rate of decay, simply differentiate the exponential equation and evaluate it at t = 0. The derivative is d C ( t) / d t = − k C ( 0) e − k t so at t = 0, the slope is simply − k C ( 0) and the magnitude of the slope is k C ( 0). With k = 0.053 s − 1 and C ( 0) = 0.4 M, this yields 0 .021 M s − 1 as the initial rate magnitude.
