In a zero order reaction, A toProducts, starting with 0.5 mol L^(-1), if 0.4 mol L^(-1) are present after 10 min., the rate constant of the reaction will be

Answer»

`0.05 MOL L^(-1) mi n^(-1)`
`0.04 mol L^(-1) mi n^(-1)`
`10^(-2) mol L^(-1) mi n^(-1)`
cannot be DETERMINED with the given data

Solution :For zero order reaction,
`k = 1/t[[A]_0-[A]]= 1/(10min)[0.5 - 0.4] mol L^(-1)`
`= 10^(-2) mol L^(-1) mi n^(-1)`
