Match the column : {:("Column-I","Column-II"),((A)DeltaH=q_p,(p)DeltaH_f^@=0),((B)"Kirchhoff's equation",(q)"A definite quantity"),((C )H^(+)(aq),(r)DeltaH_2-DeltaH_1=DeltaC_P(T_2-T_1)),((D)"Spontaneous process",(s)DeltaGgt0),(,(t)DeltaS_("Total")^@ gt0):}

Answer»

<P>

Solution :(A)`DeltaH=q_(p)` is a definite quantity
`because` ENTHALPY is a STATE function
( B)`DeltaH_2-DeltaH_1=Delta C_p(T_2-T_1)` is Kirchhoff's equation
( C) For `H^+(AQ), DeltaH_f^@=0` as per the standard assumption
(D)For spontaneous process `DeltaGlt 0` or `DeltaS_("total")^@gt0`
