Enthalpy of CH(4)+(1)/(2)O(2)rarrCH(3)OH...

Enthalpy of `CH_(4)+(1)/(2)O_(2)rarrCH_(3)OH` is
negative. If enthalpy of combustion of `CH_(4)` and `CH_(3)OH` are `x` and `y` respectively, then which relation is correct?

A

x gt y

B

x lt y

C

x = y

D

`x le y`

Text Solution

Verified by Experts

The correct Answer is:
B

`CH_4 + 1/2O_2 to CH_3OH`
`DeltaH=x-y` given `DeltaH= -ve`
hence x-y lt 0 x lt y
