Q$\mathrm{.}59$ Consider the following two parallel ireversible first order reactions at temperature T$,$k$($Round off to two decimal places$)$Rwhere k and k are the rate constants and their values are $5$ x $10$ and $15$ x $10*$ min.respectively, at temperature T$.$ If the initial concentration of the reactant $\text{'}$P$\text{'}$ is $4$ mol L$\text{'}1$then the concentration of product $\text{'}$R$\text{'}$ after $10$ min of reaction is$($Assume only P is present at the beginning of the reaction.$)$mol L$1$
