Dieterici's equation of state is P·ea/VRT (v − b) = RT, where V is the molar volume of gas. What is the pressure exerted by the gas in a vessel of 410.5 l capacity at 27°C, if P → 0?
Options:
Answer:
A
Solution:
In the limit P → 0 the gas behaves ideally: ea/VRT → 1 and b is negligible against V, so the equation reduces to PV = RT (one mole, molar volume basis). P = (RT)/V = (0.0821 × 300)/410.5 = 0.06 atm. Ans: (a)
