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: E_(cell)^(@) is negative for electrolytic cell. STATEMENT-2: /_\G^(@) is +ve for electrolyte cell
STATEMENT-1: E_(cell)^(@) =0 for a chloride ion concentration cell. STATEMENT-2: For this concentration cell where E_(cell)=(RT)/(nF)In([Cl^-]_(LHS)/([Cl^-]_(RHS)
STATEMENT-1 : The de-Broglie wavelength of an electron decreases as kinetic energy decreases. and STATEMENT- 2 : The de-Broglie wavelength lambda= ( h)/(sqrt( 2mKE))
STATEMENT-1: The voltage of mercury cell remains constant for longer period of time. STATEMENT-2: It is because net cell reaction does not involve ions.
STATEMENT-1: |(dvecv)/(dt)| is equal to (d)/(dT)|vecv| . Here vecv has its usual meaning. STATEMENT-2: If a particle si acted upon by a external force its momentum must change.
Statement-1: E_(cell)^(0)=0 for a chloride ion concentration cell. Statement-2 : For this concentration cell where E_(cell)=(RT)/(nF)ln([Cl^(-)]_(LHS))/([Cl^(-)]_(RHS))
STATEMENT-1 : The relation vectau=(dvecL)/(dt) is applicable in centre of mass frame, even though the centre of mass is accelerating. and STATEMENT-2 : The relation vectau=(dvecL)/(dt) can be directly applied in a non-inertial frame.
STATEMENT-1: lead storage battery is a galvanic cell without salt bridge. STATEMENT-2: A secondary cell is rechargeable cell.
