A student ran the following reaction in the laboratory at 527 K:

COCl2(g) CO(g) + Cl2(g)

When she introduced 2.19 moles of COCl2(g) into a 1.00 Liter container, she found the equilibrium concentration of COCl2(g) to be 2.15 M
What is the value of k?

Question

A student ran the following reaction in the laboratory at 527 K:

COCl2(g)  CO(g) + Cl2(g) 

When she introduced 2.19 moles of COCl2(g) into a 1.00 Liter container, she found the equilibrium concentration of COCl2(g) to be 2.15 M
What is the value of k?
