Correct Answer - C
`DeltaG=DeltaH - TDeltaS`
`DeltaH = sum DeltaH_(p) - sum DeltaH_(R)`
`DeltaH =- 110.5 + 266.3 = 155.8` KJ
`DeltaS = sumS_(p) - sumS_(R)`
`DeltaS = 197.6 + 27.28 - (57.5 + 5.74) = 161.64 J//"mole" `K
For reaction to be spontaneous, `DeltaG lt 0`
`DeltaH-TDeltaS lt 0" "implies " " T gt (DeltaH)/(DeltaS) = (155800)/(161.64)=964` K
