1.

At constant pressure, the heat of formation of a compound is not dependent on temperature, when

Answer»

`DELTA C_P = 0`
`Delta C_V = 0`
`Delta C_P gt 0`
`Delta C_P lt 0`

Solution :ACCORDING to kirchhoff.s equation
`Delta H_2 = Delta H_1+ Delta C_P (Delta T)`
when `Delta C_P = 0` then `Delta H` does not DEPEND on temperature .
