An egg takes 4.0 minutes to boil at sea level where the boiling point of water is \(T_1 K\), where as it takes 8.0 minutes to boil on a mountain top where the boiling point of water is \(\mathrm{T}_2 \mathrm{~K}\). The activation energy for the reaction that takes place during the boiling of egg is

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
