A) 1059 K
B) 30.5 K
C) 28.8 K
D) 28800 K
Correct Answer: A
Solution :
Key Idea: Use the following formula to solve the problem. \[\Delta S=\frac{\Delta H}{T}\] Given, \[\Delta S=\] change in entropy \[=28.8\,J{{K}^{-1}}\] \[=28.8\times {{10}^{-3}}kJ\,{{K}^{-1}}\] \[\Delta H=\] change in enthalpy \[=30.5\,kJ\,mo{{l}^{-1}}\] r = temperature \[\therefore \] \[28.8\times {{10}^{-3}}=\frac{30.5}{T}\] or \[T=\frac{30.5}{28.8\times {{10}^{-3}}}\] \[=1.059\times {{10}^{3}}\] = 1059 KYou need to login to perform this action.
