JEE Advanced Model Paper 11 with solutions for online practice

Gaseous COF2 is passed over a catalyst at 1000°C and comes to equilibrium 2COF2(g) ⇌ CO2(g) + CF4(g) . The pressure under equilibrium = 10 atm. A sample ofthe equilibrium mixture is quickly “fronzen” i.e., cooled to a low temperature.This prevents any change in the equilibrium concentrations. Analysis of 500 ml(STP) of the equilibrium mixture shows that the combined volumes (STP) of CO2 and COF2 (g) is 300 ml. Calculate Kp .
