Chemical Kinetics Question 228

Question: The concentration of a reactant decreases from 0.2 M to 0.1 M in 10 minutes. The rate of the reaction is

Options:

A) 0.01 M

B) $ {10^{-2}} $

C) 0.01 mol $ d{m^{-3}},{{\min }^{-1}} $

D) 1 mol $ d{m^{-3}},{{\min }^{-1}} $

Show Answer

Answer:

Correct Answer: C

Solution:

Rate of reaction = $ \frac{dx}{dt}=[ \frac{0.2-0.1}{10} ]=\frac{0.1}{10} $

$ =0.01mold{m^{-3}},mi{n^{-1}} $
