The rate constant for a reaction of zero order in A is 0.0030 mol L-1 s-1. How long will it take for the initial concentration of A to fall from 0.10 M to 0.075 M?
Answer & explanation
Correct answer: option 1
For zero order reaction,
k = \(\frac{1}{T}\)[Ao - A]
k = \(\frac{1}{0.003}\)[0.10 - 0.075] = \(\frac{25}{3}\) = 8.3 seconds
