Rate constant for a reaction is \(4.5\times10^{-4} mole\text{ } litre ^{-1}s^{-1}\). .If the reactant has 0.40M concentration after "5" minutes then initial concentration of it is

The rate constant for a zero order reaction is 2xx10^(-2) mol L^(-1) sec^(-1) . If the concentration of the reactant after 25 sec is 0.5 M , the initial concentration must have been:

Rate for a zero order reaction is 2xx10^(-2) mol L^(-1) s^(-1) . If the concentration of the reactant after 25s is 0.5M , the initial concentration must have been

The rate constant of the reaction A to B is 0.6xx10^(3) mole per litre per second. If the concentration of A is 5 M, then concentration of B after 20 minutes is

The rate constant of a zero order reaction is 0.2 mol dm^(-3) "min"^(-1) if the concentration of reactants after 30 minutes in 0.5 mol dm^(-3) then the initial concentration would be

The rate constant of the reaction A rarr 2B is 1.0 xx 10^(-3) mol "lit" ^(-1)" min"^(-1) , if the initial concentration of A is 1.0 mole lit^(-1) . What would be the concentration of B after 100 minutes.
