10 g of argon gas is compressed isothermally and reversibly at a temperature of 27ºC from 10 L to 5L. Calculate enthalpy change. Assume ideal behaviour ( Δ H) for this process R = 2.0 cal K –1 mol –1 . log 10 2 = 0.30 ( Atomic mass of Ar = 40)
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(Zero)
For reversible isothermal compression, ( Δ U = 0)
Also at constant temperature
PV = constant
∴ Δ H = Δ U + Δ (PV) = 0 + 0 = 0
