Chemistry Question on Equilibrium

For the reaction, C(s)+CO2(g)2CO(g),C_{(s)}+CO_{2(g)} \rightarrow 2CO_{(g)}, Kp=63K_p = 63 atm at 1000K1000\, K. If at equilibrium PCO=10Pco2,P_{CO} = 10\, P{co_2}, than the total pressure of the gases at equilibrium is

A

6.3 atm

B

6.93 atm

C

0.63 atm

D

0.693 atm

Answer

6.93 atm

Explanation

Solution

Kp=pCO2PCO2K_p = \frac{p^2_{CO}}{P_{CO_2}} 63 = l00x or x = 0.63
Total equilibrium pressure = 6.3 + 0.63 = 6.93 atm
