A chemical reaction is known to be of zero-order with k = `5 xx 10^(-8)" mole lit"^(-1) s^(-1)` .
(a) How long does it take for reactant concentration to decrease from `4 xx 10^(-4)" mole lit"^(-1) ` to `2 xx 10^(-4) "mole lit"^(-1)` ?
(b) Will the time to decrease the reactant concentration from `2 xx 10^(-2) "mol lit"^(-1)` to `1xx 10^(-2) "mole lit"^(-1)` be the same as in (a)?

Explanation

`4 xx 10^3 s, No`
