Isochoric Conditions

Postby Aya Shokair- Dis 2H » Mon Feb 12, 2018 5:35 pm

In isochoric conditions, the change in V is constant/zero. Thus, that means there must be a change in P.
However, we can calculate the change in enthalpy by using this formula: delta H= nC(p)delta T
In the formula we are assuming constant P, but that isn't the case right?
Can someone explain that to me please?

I would assume you can't use that formula since the pressure is changing. Therefore, I believe you cannot solve for enthalpy of the reaction due to the fact that the pressure is not constant (therefore q =/= deltaH).
