Answer #1

Reactants A and B and products C and D are in dynamic equilibrium, with constant concentrations.

i.e. A + B C + D

If you disturb the equilibrium by adding more of product C, then the reaction will shift in backward direction in order to re-establish the equilibrium. The equilibrium position will move so that the concentration of C decreases again by reacting it with D to form more A and B. hence, after equilibrium that is re-established, the concentrations

will be higher for A, B and C but lower for D compared to the first equilibrium.

At equilibrium, the concentrations of reactants and products can be predicted using the equilibrium constant, Kc, which is a mathematical expression based on the chemical equation. For example, in the reaction aA+bB⇌cC+dD where a, b, c, and d are the stoichiometric coefficients, the equilibrium constant is where [A], [B], [C], and [D] are the equilibrium concentrations. If the reaction is not at equilibrium, the quantity can still be calculated, but it is called the reaction quotient, Qc, instead of the...

For a general chemical equation A+B⇌C+D the equilibrium constant can be expressed as a ratio of the concentrations: Kc=[C][D]/[A][B] If this is an elementary chemical reaction, then there is a single forward rate and a single reverse rate for this reaction, which can be written as follows: forward rate=kf[A][B] reverse rate=kr[C][D] where kf and kr are the forward and reverse rate constants, respectively. When equilibrium is reached, the forward and reverse rates are equal: kf[A][B]=kr[C][D] Thus, the rate constants are...

For chemical reactions where all reactants and products are in the gas phase the amount of each gas in the vessel can be expressed either as partial pressures or as concentrations. As such the equilibrium constant for a gas phase reaction can also be expressed in terms of concentrations or pressures.
