Question

For a reversible reaction , the  forward reaction . The activation energy of the uncatalyzed forward reaction is . When the reaction is catalysed keeping the reactant concentration same, the rate of the catalysed forward reaction at  is found to be same as that of the uncatalyzed reaction at . The activation energy of the catalysed backward reaction is .

Step 1 — Find  of catalysed forward reaction:

Rate of catalysed at 300 K = Rate of uncatalysed at 600 K:

Wait — using the equation directly:

Step 2 — Find  of catalysed backward reaction:

For the uncatalysed reaction:

The catalyst lowers both forward and backward  by the same amount:

Answer: 130 kJ/mol
