Phosgene, a toxic gas, decomposes at 800°C according to COCl2(g) CO(g) + Cl2(g)....?

Question

A sample of COCl2(g) in a reaction vessel at an initial concentration of 0.500 M is heated to 800°C. The equilibrium concentration of CO(g) was found to be 0.046 M. What is the equilibrium constant for the reaction at 800°C?

A. 0.00047
B. 0.0047
C. 0.047
D.0.00094

Answer 1

For reaction aA <--> bB + cC, the Eq.constant K is defined as

K = (B^b * C^c) / A^a

Since in your equation a=b=c=1, and concentration for B=C, the equation simplifies to

K = B^2 / A

with B=0.046 and A=0.454 (0.454=0.500-0.046)

so K = 0.046^2 / 0.454 = 0.0047

Answer 2

I could be making a mistake but the answer that I get is not on here. you would write the full reaction and make sure that the reaction is balanced. Then you ICE....which means initial, change and equalibrium. The initial concentration of .5 goes under the I column and the equilibrium concentration of CO goes under the E column. Do the math.

K eq = prdocuts/ reactants
