How is equilibrium constant expression written?

For gases, the equilibrium constant expression can be written as the ratio of the partial pressures of the products to the partial pressures of the reactants, each raised to a power matching its coefficient in the chemical equation.

What is the equilibrium law expression?

The equilibrium law expression is a mathematical expression that show the ratio of products and reactants in a chemical reaction at equilibrium.

What is the equilibrium of H2?

The equilibrium constant expression is the quotient of product equilibrium concentration to reactant equilibrium concentrations as determined from the balanced chemical equation. and the [H2]eq = 0.012 M, [I2]eq = 0.15 M and [HI]eq = 0.30 M.

How do you write the equilibrium expression?

In order to write the equilibrium expression for a system in a state of equilibrium you need to know: the balanced equation for the reaction. the phases (solid, liquid, gas, or dissolved) of each species involved in the reaction.

How do you calculate the equilibrium constant of a reaction?

Kp = Kc(RT)n where n = moles of gaseous products – moles of gaseous reactants For reactions involving both gases and aqueous solutions, molar concentrations and partial pressures can appear in the equilibrium constant expression. Important points about equilibrium constants:

What is the numerator of the equilibrium constant expression?

The numerator of the equilibrium constant expression is the product of the concentrations of the “products” of the reaction raised to a power equal to the coefficient for this component in the balanced equation for the reaction.

Is the rate-determining step for forward reaction and reverse reaction always identical?

First of all, this derivation of the equilibrium constant assumes that the rate-determining step for the forward reaction and reverse reaction are always identical(the ${r}$th step). Is this always true? For example, in the reaction shown below, the 2nd step is the rate-determining step for both forward reaction and reverse reaction.
