Chemistry 340 Physical Chemistry for Biochemists One mole of nitrogen is allowed to expand from 0.5 to 10 L. Calculate the change in entropy using the ideal gas law. (a) Integrate the Gibbs-Helmholtz equation to obtain an expression for ∆G2 at temperature T2 in terms of ∆G1 at 1 T , assuming ∆H is independent […]
Make a simplified sketch of a thermal power machine where sizes W, Qh and Qc are included. Define the sizes and write down the expression for the efficiency of the thermal power machine.
A)2.00 g of helium gas at 100 ° C and a pressure of 1.00 atm expand in an isobar process so that the volume of the gas doubles. Helium is a monatomic gas with a molar mass of 4.00 g per mole. Find the following: 1.the temperature of the gas after expansion work performed on […]
