Problem 4D.7

Postby nehashetty_2G » Sat Feb 01, 2020 4:25 pm

The question asks for the delta U, but they just give us the delta H and the equation. I don't understand how you calculate this? Can we just assume delta U = delta H? And if so, why?

The equation for deltaU is q + w. q is equal to deltaH, so you would have to calculate w by using the PV=nRT equation. Then add to calculate deltaU.
