For the reaction, C(s) + CO2(g) 2CO(g), p K 63atm at 1000 K. If at equilibrium CO CO p 10p , than the total pressure of the gases at equilibrium is (KERELA CEE 2011)
A.6.3 atm
B.6.93 atm✓ Correct
C.0.63 atm
D.0.693 atm
Explanation
CHEMICAL EQUILIBRIUM 63 2 2 2 2 2 2 2 p 2 2 co CO p CO CO CO CO CO CO tot C(s) CO (g) 2CO(g) : K 63 (10P ) P K = =100P 63 P P 63 P atm 0.63atm 100 P 10P 10 0.63 6.3atm P 0.63atm 6.3atm 6.9atm >> x Hence, the correct answer is option (b)
