Questions
Suppose a diatomic gas gets ionised to a certain extent without any expenditure of heat energy. If the fractional change in the number of moles of the gas be , then ignoring any energy loss, the fractional change in the temperature of the gas will be
detailed solution
Correct option is B
Initially, E = no(52RT)------(i)Given ∆nno = η or, ∆n = ηnoNumber of moles of O2 left = (1-n)no∴ Finally, E = (1-η)no(5RT'2)+(2ηno)(3RT'2)-----(ii)Equating equations (i) and (ii), T' = 5T5+ηFractional change in temperature = T'T = 1 = -ηη+5Talk to our academic expert!
