Question

Plot dS(T) for a substance with C= a + bT+ cT^2 over a range of T = 100K to T = 400K.

• Evaluate the entropy chage of 1 mol of carbon dioxide treated as a VdW gas as it expands from 1L to 10L at 400K. • Plot dS(T) for a substance with C = a + bT + cT^2 over the range T = 100K to T = 400K. Use the following values for the constants o a = 100, b = .1, c = .03 o a = 5000, b = 10, c = .008 o a = -100, b = 10, c = -.002 aGm • The pressure dependence of the molar Gibbs Energy is given by Vm- o Consider a Van der Waals gas where only the repulsive term is significant. That is a = 0. Rearrange the VdW eqn and substitute into the equation above. Integrate the equation and get an expression for the Gibbs energy as a function of pressure. o Compare the answer you fınd to the same expression for an ideal gas. o Evaluate both expressions for CO2 from 10atm to 100atm at 400K.
