Questions
Four moles of hydrogen, 2 moles of helium and 1 mole of water vapour form an ideal gas mixture. What is the molar specific heat at constant pressure of mixture?
detailed solution
Correct option is D
Cv for hydrogen = 5R/2, Cv for helium = 3R/2, Cv for water vapour = 6R/2 (Cv)mix=4×5R2+23R2+1×3R4+2+1=16R7Cp+Cv+R=16R7+R=23R7Talk to our academic expert!
