DeltaH for CaCO(3)(s)rarrCaO(s)+CO(2)(g)...

`DeltaH` for `CaCO_(3)(s)rarrCaO(s)+CO_(2)(g)` is `176 kJ mol^(-1)` at `1240 K`. The `DeltaE` for the change is equal to

A

`160KJ`

B

`165.6KJ`

C

`186.3KJ`

D

`180.0KJ`

Text Solution

Verified by Experts

The correct Answer is:
A
`Delta H = Delta E + Delta nRT`
`:. Delta E = 176 - 1 xx 8.314xx8.314xx1240xx10^(-3)`
`= 165.6 kJ`
