At a particular temperature, a hypothetical chemical system has the following equilibrium molar concentrations:
[A] = 2.00 M, [B] = 4.00 M, and [C] = 3.00 M.

Calculate the value of the equilibrium constant (Keq expressed in terms of the molar concentrations) for the system if the reaction occuring were:

2A(g)C(g) + 4B(g)

Calculate the value of the equilibrium constant (Keq expressed in terms of the molar concentrations) for the system if the reaction occuring were:

C(g)4B(g) + 3A(g)

A +3C <--> 2B 
Keq= 2^2/(3x4^3) = 0.0208 (2.08x10^-2) 

3C + 2B <--> 4A 
Keq = 3^4/(4^3x2^2) = 0.316 (3.16x10^-1)
