What is the unit of catalytic reaction rate?
a) mole/time
b) mole * kg * time
c) mole * kg / time
d) other

The answer is the option "A"

Explanation:

The reaction rate is the amount of substance formed or transformed per unit of time. The catalytic action allows to increase the reaction rate or the selectivity. The units are moles / time (mol / s)

mol = moles

s = seconds

So the correct answer is "A"
