The variation of `E_("cell")` with temperature i.e., `((deltaE)/(deltaT))_(P)` is equal to :

P(E/F) is equal to :

The variation of volume V, with temperature T, keeping pressure constant is called the coefficient of thermal expansion (alpha) of oa gas, i.e., alpha=(1)/(V)=((deltaV)/(deltaT))_(P) . For an ideal gas alpha is equal to

The variation of volume V, with temperature T, keeping pressure constant is called the coefficient of thermal expansion (alpha) of a gas, i.e., alpha=(1)/(V)((deltaV)/(deltaT))_(P) . For an ideal gas alpha is equal to

The variation of volume V, with temperature T, keeping pressure constant is called the coefficient of thermal expansion is alpha=(1)/(V)((deltaV)/(deltaT))_(P) . For an ideal gas alpha is equal to

Statement : ((deltaE)/(deltaT))_(P) is called temperature coefficient of emf. Explanation : ((deltaE)/(deltaT))_(P) may be +ve, -ve and depends upon heat of reaction.

If Delta G = Delta H - T Delta S and Delta G = Delta H + T [(d(Delta G))/(dT)]_(P) then variation of emf of a cell E, with temperature T is given by:

If DeltaG=DeltaH-TDeltaS and DeltaG = DeltaH+T[(d(DeltaG))/(dT)] , then variation EMF of a cell E, with temperature T, is given by
