Chemistry Question from JEE Main 2025 · 3 April, Shift 2

A perfect gas ($0.1 \, \text{mol}$) having $\bar{C}_V = 1.50\,R$ (independent of temperature) undergoes the above transformation from point $1$ to point $4$. If each step is reversible, the total work done ($w$) while going from point $1$ to point $4$ is (−) _____ J (nearest integer)

[Given : $R = 0.082 \, \text{L atm K}^{-1} \text{mol}^{-1}$]
