#1
Front (Question)

Defn of reversible rctns

Back (Answer)

Rctns that proceed in both the forward and backward directions

#2
Front (Question)

Defn of dynamic eqm

Back (Answer)

refers to a state in a reversible system in which the rates of the forward and backward rctns are continuing at the same rate, resulting in no net change in macroscopic properties (eg conc, partial pressure) of the rcts and prods

#3
Front (Question)

Eqm can only be achieved in a ___ system

Back (Answer)

Closed system, one which does not allow matter to enter or leave but allows free transfer of energy

#4
Front (Question)

Eqn for rate of forward/backward rctn

Back (Answer)

rate = k[A][B]

#5
Front (Question)

Rctn Quotient

Back (Answer)

At any given time, aA+bB ⇌cC +dD c d [C] [D] Qc = -------------------------- , where [ ] are the conc in a b mol/d^-3 at any given time [A] [B]

#6
Front (Question)

Eqm constant

Back (Answer)

c d [C] eqm [D] eqm Kc = ——————————- , where [ ] eqm of _ are the a b conc in mol/d^-3 at eqm [A] eqm [B] eqm

#7
Front (Question)

Defn of position of eqm

Back (Answer)

Relative composition (eg conc) of the products and rcts present in a rctn mixture at eqm
