Express the molar concentration numerically using two, Ask an Expert

Academics

The reversible chemical reaction A+B <=> C+D with an equilibrium constant of K 7.1.Initially, only A and B are present, each at 2.00 . What is the final concentration of A once equilibrium is reached? Express the molar concentration numerically using two significant figures. What is the final concentration of D at equilibrium if the initial concentrations of A = 1.00M and B= 2.00M
