Question

A sample consisting of 2.0 mol CO2 occupies a fixed volume of 15.0 dm³

at 300 K.

When it is supplied with 2.35 kJ of energy as heat its temperature increases to 341 K.

Assuming that CO2 is described by the van der Waals equation of state, calculate w,

ΔU, and ΔH.

Answer 1

Here is a start for you;

W = PdV

V is fixed

dV=0

therefore W=0

U = Q+W = Q+0 =Q
