Question

Feo + co = Fe + CO
fe is
initially (1.4)
and co2 (0.8)
What are eq Partial Press on co&CO2​

Answer 1

ANSWER:

The initial partial pressures of CO and CO2are 1.40 atm and 0.8. atm respectively.

The expression for the reaction quotient is :

Qp = PCO2 0.80

---------- = -------- = 0.571

PCO 1.4

As the value of the reaction quotient is greater than the value of the equilibrium constant, the reaction will move in the backward direction.

To attain the equilibrium, the partial pressure of CO2will decrease and the partial pressure of CO will increase. Let p atm be the decrease in the partial pressure of CO2. The increase in the partial pressure of CO will be p atm.

The equilibrium partial pressure of CO2 is 0.80-p atm.

The equilibrium partial pressure of CO is 1.4 + p atm.

The equilibrium constant is: = PCO2 0.80-p

----------- = ----------- = 0.265

PCO 1.4+p

0.265 (1.4+p) = 0.80-p

0.371 + 0.265p = 0.80-p

P = 0.339atm

The equilibrium partial pressure of CO is 1.4+0.339=1.739.

The equilibrium partial pressure of CO2 is 0.80−0.339=0.461 atm.
