1.	The heat of formation of C2H5OH(l) is −66 kcal mol−1. The heat of combustion of CH3OCH3 (g) is −348 kcal mol−1. △Hf for H2O and CO2 are −68 kcal mol−1 and −94 kcal mol−1 respectively.Then, the △H for reaction C2H5OH(l)→CH3OCH3(g) is :
Answer» The heat of formation of $C_{2} H_{5} O H (l)$ is $- 66 k c a l m o l^{- 1}$ . The heat of combustion of $C H_{3} O C H_{3} (g)$ is $- 348 k c a l m o l^{- 1}$ . $△ H_{f}$ for $H_{2} O$ and $C O_{2}$ are $- 68 k c a l m o l^{- 1}$ and $- 94 k c a l m o l^{- 1}$ respectively. Then, the $△ H$ for reaction $C_{2} H_{5} O H (l) \to C H_{3} O C H_{3} (g)$ is :
