Studying the CLEP and would love a rationale for this sample question...please and thank you! :)

R(g) + 2T(g) - 2X(g) + Z(g)
The reaction mixture represented above is at equilibrium at 298 K. The value of the equilibrium constant for the reaction is 16 at 298 K. If R(g), X(g) and Z(g) each have an equilibrium concentration of 2.0 M, what is the equilibrium concentration of T(g)?

preetha · Answer

Write the equation for the eq constant Keq = [X]2[z]/[R][T]2
Should be able to plug it in.
