The values of DeltaH and DeltaS for the ...

The values of `DeltaH` and `DeltaS` for the reaction,
`C_("graphite")+CO_(2)(g)rarr2CO(g)`
are `170KJ` and `170JJK^(-)` respectively. This reaction will be spontaneous at

A

710 K

B

910K

C

1110 K

D

510 K

Text Solution

Verified by Experts

The correct Answer is:
C
`Delta G= Delta H- T Delta S`
`= (170 xx 10^(3)J) - T(170 JK^(-1))`
T= 1000K
FOr spontaneity, `Delta G` is -ve
Hence T should be `gt 1000K`
