For the `C(s) + H _(2) O (g) to CO (g) + H _(2) (g )` reaction,` Delta H ^(@) = + 131kJ , Delta S ^(@) = + 134 JK ^(-1)` Mark out the correct statement(s).

Options

A. Reaction is spontaneous even at room temperature
B. Reaction is not spontaneous at room temperature.
C. Reaction is spontaneous above `705^(@)C.`
D. Reaction is non spontaneous above `705^(@)C.`

Explanation

A process can be assumed to be at equilibrium in between a spontaneous and non-spontaneous situation.
`Delta G = DeltaH - T Delta S,` equilibrium `Delta G = 0. Delta H = T Delta S, T = DeltaH//DeltaS = 978 K = 705 ^(@)C.`
