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 :-

A

1000 K

B

900 K

C

1100 K

D

At any temperture

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaG=DeltaH-TDeltaSltO` for spontaneous process
`Tgt(DeltaH)/(DeltaS)`
`Tlt(-100xx10^(3))/(-100)`
`Tlt1000K`
