Question

If rate of a zero order reaction is 10 \(\frac{mol}{m^3×s}\) and reaction time is 5s, then the value of rate constant is ____

(a) 1 s^-1

(b) 2 s^-1

(c) 5 s^-1

(d) 10 s^-1

The question was asked in my homework.

Question is taken from Reaction Kinetics Elements in section Elements of Reaction Kinetics of Chemical Reaction Engineering

Answer 1

Correct option is (b) 2 s^-1

To explain I would say: (-rA) = kCA^n

10 = k (5)

Hence, k = 2 s^-1.
