Consider the reaction, `N_(2) (g)+3H_(2)(g)to 2NH_(3)(g),` carried out at constant temperature and pressure. If `Delta H and DeltaU` are enthalpy change and internal energy change respectively, which of the following expressions is true?

A

`DeltaH = 0`

B

`Delta H = Delta U`

C

`Delta H lt Delta U`

D

`Delta H gt Delta U`

Text Solution

Verified by Experts

`Delta H = Delta U + Delta n RT, Delta n = 2 - 4 = - 2 therefore Delta H lt Delta H`
