Which reaction, with the following value...

Which reaction, with the following value of `DeltaH` and `DeltaS` at `350K` is spontaneous and endothermic?
`DeltaHKJmol^(-1)DeltaSKJmol^(-1)DeltaHKJ mol^(-1)DeltaSKJ mol^(-1)`

A

`-48,+135xx10^(-3)`

B

`-48,-135`

C

`+48,+135xx10^(-3)`

D

`+48,-135xx10^(-3)`

Text Solution

Verified by Experts

The correct Answer is:
D
For endothermic reaction `DeltaHgt0`
Thus, `(c)` or `(d)`
`DeltaG=DeltaH-TDeltaS`
If `TDeltaSgtDeltaH` , then `DeltaGlt0`
Thus, spontaneous
`TdeltaS=135xx10^(-3)xx350=54KJgtDeltaH`
Thus `(c)` is correct.
