Q94 · Chemistry

Hydrolysis of sucrose is given by the following reaction.

Sucrose + H2O⇌\mathrm{H_2O \rightleftharpoons} Glucose + Fructose

If the equilibrium constant (KcK_c) is 2×10132\times10^{13} at 300 K, the value of ΔrG⊖\Delta_rG^\ominus at the same temperature will be :

  1. 1−8.314-8.314 J mol−1^{-1}K−1×300^{-1}\times300 K×ln⁡(2×1013)\times\ln(2\times10^{13})Official answer
  2. 28.3148.314 J mol−1^{-1}K−1×300^{-1}\times300 K×ln⁡(2×1013)\times\ln(2\times10^{13})
  3. 38.3148.314 J mol−1^{-1}K−1×300^{-1}\times300 K×ln⁡(3×1013)\times\ln(3\times10^{13})
  4. 4−8.314-8.314 J mol−1^{-1}K−1×300^{-1}\times300 K×ln⁡(4×1013)\times\ln(4\times10^{13})
