The reaction for the formation of gaseous hydrogen fluoride has an equilibrium constant of KC = 1.15×10^2 at a given temperature. Assuming that the reaction starts by adding 3.00 moles of each component (H2, F2, and HF) to a 1.5-L reactor, calculate the equilibrium concentration of hydrogen fluoride.
H2(g) + F2(g) <--> 2 HF(g)
