The rate constant of the reaction A to B is 0.6 x 10^-3 Molar per second. If the concentration of A is 5 M then concentration of B after 20 minutes is

Answer»

1.08 M
3.60 M
0.36 M
0.72 M

Solution :It is zero order reaction `THEREFORE 6 XX 10^(-4) = ("con")/(20 xx 60)`
`therefore` Conc., of B = 0.72 M
