JEE PYQ: Chemical Equilibrium Question 8
Question 8 - 2021 (24 Feb Shift 1)
For the reaction $\text{A}{(g)} \rightarrow \text{B}{(g)}$, the value of the equilibrium constant at 300 K and 1 atm is equal to 100.0. The value of $\Delta_r G$ for the reaction at 300 K and 1 atm in J mol$^{-1}$ is $-xR$, where $x$ is ____. (Rounded off to the nearest integer)
$[R = 8.31 \text{ J mol}^{-1} \text{K}^{-1}$ and $\ln 10 = 2.3]$
Show Answer
Answer: 1380
Solution
$\Delta G^\circ = -RT \ln K_{eq} = -R \times 300 \times 2 \times 2.3 = -1380R$. So $x = 1380$.
