Problem: A sample of C2H2 (g) has a pressure of 7.6 kPa . After some time a portion of it reacts to form C6 H6 (g). The total pressure of the mixture of gases is then 4.0 kPa . Assume the volume and the temperature do not change.Find the mole fraction (in percents) of C2 H2 (g) that has undergone reaction.
