Mixture of voltaic component A and B has total vapure pressure (in torr) P = 254 - 119 X A . Where X A is mole fraction of A in the mixture. Hence, P A 0 & P B 0 (in torr) are:

Options

  1. A254 , 199
  2. B119 , 254
  3. C135 , 254
  4. D119 , 373

Correct answer

C. 135 , 254

Step-by-step solution

For X A = 0 ,  P B 0 = 254 For X A = 1 ,  P A 0 = 254 – 119   = 135
