Question
The values of enthalpies of reactants and products are x and y J/mol, respectively. If the activation energy for the backward reaction is z J/mol, then the activation energy for forward reaction will be (in J/ mol)
Options
A.x − y − z
B.x − y + z
C.y − x − z
D.y − x + z
Solution
$\Delta H = E_{af} - E_{ab} \Rightarrow y - x = E_{af} - z \Rightarrow E_{af} = y - x + z$
