A hypothetical reaction Ato2B, proceeds ...

A hypothetical reaction `Ato2B`, proceeds through following sequence of steps
(i) `A to C,DeltaH=q`
(ii) `C to D,DeltaH=v`
(iii) `(1)/(2)D to B,DeltaH=x`
Then, the heat of reaction is

A

`q-v+2x`

B

`q+v-2x`

C

`q+v+2x`

D

`q+2v-2x`

Text Solution

Verified by Experts

The correct Answer is:
C
According to Hess's law, the total heat changes occurring during a chemical reaction are independent of path.
`DeltaH=q+v+2x`
