The rate constant of the reaction `A rarr B` is `0.6 xx 10^(-3)` mole per second. If the concentration of `A` is `5 M`, then concentration of `B` after `20` minutes is:A. 0.36 MB. 0.72 MC. 1.08 MD. 3.60 M |

Answer» Correct Answer - B Zero order reaction x=kt `x=0.6xx10^(-3)xx20xx60` `=72xx10^(-2)` x=0.72M `{:(,Ato,B),("Initial case",5,0),("After 20 min.",5-x,x):}` So, [B]=x=0.72M |
