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`

Delta U=0 for

A reaction attains equilibrium state under standard conditions, then A) equilibrium constant K=0 B) equilibrium constant "K=1 C) Delta G^(o)=0 and Delta H^(o)=T Delta S^(o) D) Delta G=0 and Delta H = T Delta S

The process in which the value of Delta U=0 is :

A porcess is nonspontaneous at evey temperature if (i) Delta H gt 0, Delta S = 0 (ii) Delta H lt 0, Delta S gt 0 (iii) Delta H gt 0, Delta S lt 0 (iv) Delta H = 0, Delta S lt 0

For the reaction, A(s) + 3B(g) rarr 4C(g) + d(l) Delta H and Delta U are related as :

Delta H f^(0) of diamond is
