For the chemical equilibrium, CaCO(3)(...

For the chemical equilibrium,
`CaCO_(3)(s) hArr CaO(s)+CO_(2)(g)`
`Delta_(r)H^(ɵ)` can be determined from which one of the following plots?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
`CaCO_(3)(S)harrCaO(S)+CO_(2)(g)`
`K_(P)=P_(CO_(2))`
`log K_(P)=logA-(DeltaH_(r)^(0))/(2.303RT)`
`log P_(CO_(2))=logA-(DeltaH_(r)^(@))/(2.303) (1)/(RT)......(i)`
Graph `(a)` represents `(i)` and its slope will be used to determine he heat of the reacion.
