1 consider 2kg mixture of h2 and n2 ideal gases

Question

1) Consider 2kg mixture of H₂ and N₂ ideal gases inside a closed piston-cylinder device at 150kPa and 100o C. This mixture has 0.4 mole fraction of H₂. This mixture undergoes a constant pressure heating process to final temperature 180° C (inside the piston-cylinder device) . For this mixture,

i) determine R, M, C_v and initial volume of the mixture.

ii) Heat energy added to the mixture.

iii) Work done during the heating process.
