The value of `DeltaH` and `DeltaS` for the reaction
`C_"(graphite)"+O_(2(g))to CO_(2(g))` are -100JK and `-100JK^(-1)`
respectively. The reaction will be spontaneous at :-

Options

A. 1000 K
B. 900 K
C. 1100 K
D. At any temperture

Answer

B

Explanation

`DeltaG=DeltaH-TDeltaSltO` for spontaneous process
`Tgt(DeltaH)/(DeltaS)`
`Tlt(-100xx10^(3))/(-100)`
`Tlt1000K`
