Problem
For the endothermic reaction
C ⇌ D
at 298 K, the forward and reverse rates are equal. When the temperature is raised to 318 K, the forward rate increases by 40 %, while the reverse rate increases by 10 %. Which statement correctly predicts the direction of net conversion immediately after the temperature change?
(a) No net conversion occurs because both the forward and reverse rates have increased, so the system remains at equilibrium.
(b) Net conversion of C to D occurs because the forward rate now exceeds the reverse rate.
(c) Net conversion of D to C occurs because raising the temperature favors the exothermic reverse reaction.
(d) The direction cannot be predicted without knowing activation energies.
