The values of DeltaH and DeltaS for the ...

The values of `DeltaH` and `DeltaS` for the reaction
`C("graphite")+CO_(2)(g)to2CO(g)` are `170 kJ` and `170 JK^(-1)` respectively. The reaction will be spontaneous at

A

510 K

B

170K

C

910K

D

1110K

Text Solution

Verified by Experts

The correct Answer is:
D
For a spontaneous reaction
`DeltaG=-ve `
Or ar eq. `DeltaG=0`
`Delta H=T DeltaS `
`T=(DeltaH)/(DeltaS)`
`=(170xx10^(3))/(170)`
`=1000K`
