1.	Consider the reaction, `N_(2)(g)+3H_(2)(g)rarr2NH_(3)(g)`, carried out at constant temperature and pressure. If `Delta H` and `Delta U` are enthalpy change and internal energy change respectively, which of the following expressions is true ?A. `Delta H=0`B. `Delta H=Delta U`C. `Delta H lt Delta U`D. `Delta H gt Delta U`
Answer» Correct Answer - C `N_(2)+3H_(2)rarr2NH_(3)" " Deltan=2-4= -2` `Delta H=DeltaU+Delta nRT=Delta U-2RT" " :. Delta H lt Delta U`
