The `emf` of given cell `Pt - underset(P_(1))(H_(2))|H^(+)|underset(P_(2))(H_(2) - Pt` is :

The emf of the cell Pt, underset(1atm)(H_(2(g)))|underset(.01M)(HA)||underset(1M)(HCl)|H_(2(g)),Pt is 0.295V. Dissociation constant of the acid HA is ...

Find out given cell is spontaneous or non-spontaneous underset(P_(1))(H_(2)//H^(@)) || underset(P_(2))(H^(+)//H_(2)) . If P_(1) gt P_(2)

For the given cell, underset(P_(1))(Pt,C1_(2))|underset(C_(1))(HC1)||underset(C_(2))(HC1)|underset(P_(2))(C1_(2),Pt) The emf will be positive when :

The emf of given cell Pt- H_2 | H^+|H_2 - Pt is :

overset(H_(2)("1 mole"))underset(Pt)(to)(A) , product (A) is:
