The time for half-life period of a certain reaction A to products, is 1 hour. When the initial concentration of the reactant, A is 2.0 mol L^(-1), how much time does it take for its concentration to come from 0.50 to 0.25 mol L^(-1) if it is a zero-order reaction?

Answer»

4 h
0.5 h
0.25 h
1 h

Solution :For zero-order REACTION, `t_(1//2)PROPA`
