The following liquid phase reaction $2A+BC$ was carried out in a constant volume batch

laboratory reactor where a $25ml$ of $2\mathrm{.}0M(2$Kmo$\frac{l}{m^3})$ of A was mixed with $975ml$ of $B.$ The

temperature was kept at $40C.$ The concentration of product $C$ was recorded and tabulated as a

function of time $($as below$).$

Kmo$\frac{l}{m^3}=mo\frac{l}{l}$iter,$1$ liter $=1000ml$

If the reaction is Second order with respect to A and Zero order to B$,$ what is the specific reaction

rate constant?
