Statement-1: if `((dE_(cell))/(dT))_(p)gt0` for a cell reaction then `triangleS` is positive.
Statement-2: `triangleS=nFT((dE)/(dT))_(p)`

The questions consist of two atatements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses : Ig ((dE_(cell))/(dT))_pgt 0 for a cell reaction then Delta S is positive . Delta S= nFT ((dE)/(dT))_p .

STATEMENT-1: If ((dE_(cell))/(dT))_Pgt0, For a cell reaction then /_\ S is positive. STATEMENT-2: /_\SnFT((dE)/(dT))_p

If Delta G^(@)gt 0 for a reaction then :

Statement-1 : All the exothermic reactions are spontaneous. And Statement-2 : For a spontaneous reaction, Delta G must be negative.

Statement- 1: If the sines of the angles of a triangle are in A.P., then the altitudes ef the triangle are also in A.P. Statement-2: Twice the area of a triangle is equal to the product of the lengths of a side and the altitude on it.

Statement -I: A construction of triangle with sides measuring p,q and r units 1 s awayspossible if p+q

Pt | Cl_2 (P_2) |HCl (0.M) |Pt|Cl_2 (P_2) , cell reaction will be spontaneous if :

The cell potential (E_(cell)) of a reaction is related as /_\G=-nF E_(cell) , where /_\ G represents max. useful electrical work n=no. of moles of electrons exchanged during the section for reversible cell reaction d(/_\G)=(/_\_rV)dp-(/_\_rS),dT at constant pressure d(/_\G)=-(/_\_rS).dT :' At constant pressure /_\G=/_\H-T./_\S :. /_\G=/+\H+T(d(/_\G))/((dT)_P) ((dE_(cell))/(dT))_P is known as temperture coefficient of the e.m.f of the cell. The temperature coefficient of the e.m.f of cell, ((dE)/(dT))_P si given by:
