In the reaction C((s)) +O(2(g)) rarr CO(...

In the reaction `C_((s)) +O_(2(g)) rarr CO_(2(g)), Delta H =-94.3` Kcal

A

`H_(P) gt H_(R)`

B

`H_(P) lt H_(R)`

C

`H_(P) = H_(R)`

D

`H_(P)=2H_(R)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Delta H = Sigma Hp- Sigma H_(R)`
`-94.3=H_(p)-H_(R)`
`therefore H_(R)=H_(p)+94.3 therefore H_(p) lt H_(R)`
