An endothermic gaseous reaction,
`(1)/(2)X+Y to2Z`
proceeds spontaneously at `27^(@)C` because

A

`DeltaH lt 0` , `DeltaS lt 0`

B

`DeltaH gt 0` , `DeltaS gt 0`

C

`DeltaH lt 0` , `DeltaS gt 0`

D

`DeltaH gt 0` , `DeltaS lt 0`

Text Solution

Verified by Experts

The correct Answer is:
B

Since the process is endothermic, therefore `DeltaH gt0`. For endiothermic process to be spontaneous `DeltaS gt 0 (T DeltaS gt DeltaH)`.
