Consider the reaction: A(g) + B(b) <-> C(g)
for which K=130. assume that .406 mol of C(g) is placed in a cylinder that has a massless, frictionless piston. the temp is 300 K and the barometric pressure on the piston is constant at 1 atm. the original volume (before the .406 moles decompose) is 10 L. what is the volume in the cylinder at equilibrium?
