Gibbs free energy and spontaneity ($\Delta H$ from $\Delta U$ for gaseous reactions)

2026 1 question

1. Consider the following reaction: $2A(g) + B(g) \rightarrow 2D(g)$, $\Delta U^{\ominus} = -10\ kJ\,mol^{-1}$ and $\Delta S^{\ominus} = -44\ J\,K^{-1}$ at 298 K. Identify the CORRECT option with $\Delta G^{\ominus}$ for the reaction and spontaneity of the reaction at 298 K. [Given: $R = 8.31\ J\,mol^{-1}\,K^{-1}$]
