Question

The rate constant of the reaction A→B is 0.6×10−3mole per second. If the concentration of A is 5 M, then cencentration of B after 20 minutes is -

Answer 1

The units of a reaction rate are concentration / time. This is most often M / s, where M is molarity (moles per liter) and s is time in seconds.

P.S. Don’t get M / s (molarity per second) confused with m / s (meters per second)
