For the equations
`C1 ("diamond") +2H_(2)(g)rarrCH_(4)(g),DeltaH_(1)`
`C(g)+4H(G)rarrCH(g),DeltaH_(2)1`
Predict whether

A

`DeltaH_(1)=DeltaH_(2)`

B

`DeltaH_(1)gt DeltaH_(2)`

C

`DeltaH_(1)lt DeltaH_(2)`

D

`DeltaH_(1)=DeltaH_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D

`DeltaH_(1)gtDeltaH_(2)` . As diamond has got more strength of bonding in it.
