Constant Volume

Postby 104969854 » Tue Feb 13, 2018 1:02 pm

At constant volume, are q, deltaU, and delta H all equal?

At constant volume, w = 0, therefore, the equation delta U = q +w would be delta U = q. However, q would only be equal to delta H if the reaction was also at constant pressure.

When w = 0, delta U = q.
q is only equal to delta H when it is q is at constant pressure.
