Initially, only A and B are present, each at 2.00 M.
What is the final concentration of A once equilibrium is reached?
Express your answer to two significant figures and include the appropriate units.
What is the final concentration of D at equilibrium if the initial concentrations are [A] = 1.00 M and [B] = 2.00 M?
Express your answer to two significant figures and include the appropriate units. Kc=[C][D]/[A][B]=7.2
