In a specialty gas preparation plant, gas cylinders are filled with a mixture of 10% H2 and90% N2 (mole percentages - also known as "forming gas"). A gas cylinder can

fit approximately 300 mol. Initially, the two gases are mixed at 25 °C and 1 bar. What is the enthalpy change? Why? (3 pt) B. Calculate the entropy change upon mixing of the two gases. (7 pt) C. The molar entropy of pure H2 at 25 °C and 1 bar is the partial molar entropy of H2 in the mixture at 25 °C and 1 bar. i. Greater than ii. Less than iii. Equal to D. The molar enthalpy of pure H2 at 25 °C and 1 bar is isentropy of H2 in the mixture at 25 °C and 1 bar. (2 pt)the partial molar i. Greater than ii. Less than iii. Equal to E. After the initial mixing, the gases are compressed to 200 bar and cooled back down to 20 .c calculate the fugacity coefficient of the two gases you may assume the lewis fugacity rule The molar entropy of pure N2 at 25 °C and 200 bar isentropy of N2 in the mixture at 25 °C and 200 bar. (2 pt)the partial molar i. Greater than ii. Less than iii. Equal to The molar enthalpy of pure N2 at 25 °C and 200 bar is ---- the partial molar entropy n2 in the mixture at 25 .c and 200 bar i. Greater than ii. Less than Equal to
