The entropy and enthalpy changes for the reaction $\mathrm{CO}(g)+\mathrm{H}_2 \mathrm{O}(g) \rightleftharpoons \mathrm{CO}_2(g)+\mathrm{H}_2(g)$ at 300 K and 1 atm are respectively $-42.4 \mathrm{JK}^{-1}$ and -41.2 kJ. The temperature at which the reaction will go in the reverse direction is

• A

  761.8 K
• B

  671.8 K
• C

  961.8 K
• Correct answer
  D

  971.8 K

Hence, the correct answer is option: 'D'.
