JEE Main levelNumerical answerDifficulty 2 of 3td097

A reaction has $Δ H^{\circ} = + 55.3 kJ mo l^{- 1}$ and $Δ S^{\circ} = + 132.0 J K^{- 1} mo l^{- 1}$ (both independent of temperature). Above what temperature, in $K$ (nearest integer), does the reaction become spontaneous under standard conditions?

Numerical answer type, answer in K, tolerance 0.5.

Answer: 418.94 K

Δ G^{\circ} < 0

requires

T > Δ H^{\circ} /Δ S^{\circ} = 55300/132.0 = 418.9 K
