Question

For the exothermic reaction A + B arrow C + D , Δ H is the heat of reaction and Ea is the energy of activation. The energy of activation for the formation of A + B will be (A) Ea (B) Δ H (C) Ea+Δ H (D) Δ H-Ea

Tardigrade Admin · Accepted Answer

For the exothermic reaciion the energy of products is always less than the reactants. If Ea is the energy of activation for the forward reaction, the energy of activation for backward reaction is Ea+Δ H

Q. For the exothermic reaction $A + B \to C + D, Δ H$ is the heat of reaction and $E_{a}$ is the energy of activation. The energy of activation for the formation of $A + B$ will be

$E_{a}$

$Δ H$

$E_{a} + Δ H$

$Δ H - E_{a}$

For the exothermic reaciion the energy of products is always less than the reactants. If $E_{a}$ is the energy of activation for the forward reaction, the energy of activation for backward reaction is $E_{a} + Δ H$

Q. For the exothermic reaction A+B→C+D,ΔH is the heat of reaction and Ea​ is the energy of activation. The energy of activation for the formation of A+B will be

Ea​

ΔH

Ea​+ΔH

ΔH−Ea​
