For a pseudo first-order reaction, what is the unit of the rate of the reaction?(a) s^-1(b) mol L^-1s^-1(c) mol^-1 L s^-1(d) mol^-2 L^2 s^-1The question was asked in final exam.I'd like to ask this question from Chemical Kinetics topic in chapter Chemical Kinetics of Chemistry – Class 12

Answer»

Right option is (a) s^-1

The explanation is: The UNIT of the RATE of the reaction (K) is (mol L^-1)^1-N s^-1, where n is the order of the reaction.

For a pseudo first-order reaction n=1.

So, (mol L^-1)^1-n s^-1 = (mol L^-1)^1-1 s^-1 = s^-1.
