$(C= 3 \times 10^8 \,ms^{-1}$ and $N_A =6.02 \times mol^{-1}).$
${A_2}(g) + 4{B_2}(g) \rightleftharpoons 2A{B_4}(g)\,;\,\Delta H < 0$
the formation of $AB_4(g)$ will be favoured by
An ideal gas undergoes a cyclic transformation starting from the point $\mathrm{A}$ and coming back to the same point by tracing the path $\mathrm{A} \rightarrow \mathrm{B} \rightarrow \mathrm{C} \rightarrow \mathrm{A}$ as shown in the diagram. The total work done in the process is____ $J$.
