Question

Solve this: 14 g of oxygen at 0oC and 10 atm are subjected to reversible adiabatic expansion to a pressure of 1 atm.calculate the work done in
(i)Litre atm
(ii)Calorie (given cpcv=1.4)

Answer 1

If the $K_p$ for the equilibrium, $M.5H_2O(s) \rightleftharpoons M.3H_2O(s) + 2H_2O(g)$ is 1 × 10⁻⁴. Then M.5H₂O(s) will show efflorescence when it is exposed to an atmosphere where vapour pressure of water is –
(a) more than 10⁻² atm
(b) below 10⁻² atm
(c) more than 10⁻⁴ atm
(d) below 10⁻⁴ atm
