Rate of disappearance of the reactant A at two different temperature is given by `A rarr B`
`(-d[A])/(dt)=2 xx 10^(-2) "sec"^(-1)[A]-4xx10^(-3)"sec"^(-1)[B] at 300 K`
`(-d[A])/(dt)=4 xx 10^(-2) "sec"^(-1)[A]-16xx10^(-4)"sec"^(-1)[B] at 400 K` heat of reaction in the given temperature range, when equilibrium is set up is :

Options
