Vedclass · Answer

(D) The relationship between $\Delta H$ and $\Delta U$ is given by the equation: $\Delta H = \Delta U + \Delta n_g RT$. Rearranging this,we get $\Delta H - \Delta U = \Delta n_g RT$. For the reaction $2 C_{(s)} + 3 H_{2(g)} ightarrow C_2H_{6(g)}$,the change in the number of moles of gaseous species is $\Delta n_g = (n_{g, 	ext{products}}) - (n_{g, 	ext{reactants}})$. Here,$n_{g, 	ext{products}} = 1$ (for $C_2H_{6(g)}$) and $n_{g, 	ext{reactants}} = 3$ (for $H_{2(g)}$). Thus,$\Delta n_g = 1 - 3 = -2$. Substituting this value into the equation,we get $\Delta H - \Delta U = -2 RT$.

What is the value of $\Delta H - \Delta U$ for the following reaction? $2 C_{(s)} + 3 H_{2(g)} \rightarrow C_2H_{6(g)}$
