What is the pressure of a gas at T = 227^oC, it is given that A = 5, B = 4 X 104 and C = 0 if T is in kelvin and p in mm Hg?(a) 0.024 mm Hg(b) 0.049 mm Hg(c) 0.075 mm Hg(d) 0.096 mm Hg

Answer» The correct option is (b) 0.049 mm Hg

To explain: ln p* = A – B/(C + T), => ln p = 5 – 4 X 10^3/(273 +227) = -3, => p = 0.049 mm Hg.
