Write the relationship between delta H and delta U for
N2 + 3 H2 --> 2 NH3​

Answer 1

Answer:

$\textsf { \Delta H = \Delta U -2RT}$

Explanation:

We know that $\textsf { \Delta H = \Delta U - \Delta n _g RT}$

where $\Delta n_g$ = number of gaseous products - number of gaseous reactants

Here, Delta n = 2 - (3 + 1) = -2

Hence, $\textsf { \Delta H = \Delta U -2RT}$
