For `N_(2)+3H_(2)rarr2NH_(3)` ,enthalpy and internal energy changes respectively are,`Delta H&Delta U` ,then, `(A) Delta H=O` ` (B) Delta H=Delta U` (C)`Delta H`<`Delta U` (D) `Delta H`>`Delta U`

If Delta H is the change in enthalpy and Delta U the change in internal energy accompanying a gaseous reaction (A) Delta H is always greater than Delta U (B) Delta H < Delta U only if the number of moles of the products is greater than the number of the reactants (C) Delta H is always less than Delta U (D) Delta H < Delta U only if the number of moles of the products is less than the number of the reactants

For which of the following change Delta H!=Delta U ?

In which of the following Delta H = Delta U ?

For a cyclic process,the condition is (A) Delta U=0 only (B) Delta H=0 only (C) Delta U>0 and Delta H>0 (D) both Delta U=0 and Delta H=0

In which of the following, Delta U=Delta H ?
