Reversible Reaction

Definition

A reaction that can proceed in both forward and reverse directions.

1 / 7
Reversible Reaction
Not Started

A reaction that can proceed in both forward and reverse directions.

7.2.A
Dynamic Equilibrium
Not Started

A state where forward and reverse reactions continue at equal rates, so concentrations stay constant.

Product-Favored Vs Reactant-Favored
Not Started

Product-favored means equilibrium contains more products; reactant-favored means it contains more reactants.

7.2.A
Equilibrium Constant And Favored Direction
Not Started

K > 1 means product-favored, K < 1 means reactant-favored, and K = 1 means similar amounts.

7.2.A
Relative Size Of K
Not Started

Larger K values mean reactions proceed farther toward products than smaller K values do.

7.2.A
Rate And Concentration Graphs At Equilibrium
Not Started

Rates become equal over time, while reactant and product concentrations level off and remain constant.

7.2.A7.2.A.1
Relative Reaction Rates And Net Direction
Not Started

Whichever reaction rate is greater determines the net change toward products or reactants.
