Question

A sample consisting of 1 mol of a monoatomic perfect gas $\left(\begin{array}{c}{C}_v=\frac{3}{2}R\end{array}\right)$ is taken through the cycle as shown :

$\Delta H$ for the overall cycle is :

• A. $+5.67\times {10}^{3}J$
• B. $-5.67\times {10}^{3}J$
• C. $-11.34\times {10}^{3}J$
• D. 0

Answer 1

Answer: (D)

0

As we know, H is a state function so,
in cyclic process, $\Delta H=0$.
