Equilibrium Concentration of Substance A

Go Equilibrium Concentration of A = (((Equilibrium Concentration of C^No. of Moles of C)*(Equilibrium Concentration of D^No. of Moles of D))/(Equilibrium Constant*(Equilibrium Concentration of B^No. of Moles of B)))^(1/Number of Moles of A)

Equilibrium Concentration of Substance C

Go Equilibrium Concentration of C = ((Equilibrium Constant*(Equilibrium Concentration of A^Number of Moles of A)*(Equilibrium Concentration of B^No. of Moles of B))/(Equilibrium Concentration of D^No. of Moles of D))^(1/No. of Moles of C)

Equilibrium Concentration of Substance D

Go Equilibrium Concentration of D = ((Equilibrium Constant*(Equilibrium Concentration of A^Number of Moles of A)*(Equilibrium Concentration of B^No. of Moles of B))/(Equilibrium Concentration of C^No. of Moles of C))^(1/No. of Moles of D)

Equilibrium Constant with respect to Molar Concentrations

Go Equilibrium Constant = ((Equilibrium Concentration of C^No. of Moles of C)*(Equilibrium Concentration of D^No. of Moles of D))/((Equilibrium Concentration of A^Number of Moles of A)*(Equilibrium Concentration of B^No. of Moles of B))

Variation of Equilibrium Constant with Temperature at Constant Pressure

Go Equilibrium constant 2 = Equilibrium constant 1*exp((Heat of reaction/[R])*((Absolute temperature 2-Absolute Temperature)/(Absolute Temperature*Absolute temperature 2)))

Equilibrium concentration of Substance B

Go Equilibrium Concentration of B = (Equilibrium Concentration of C*Equilibrium Concentration of D)/(Equilibrium Constant*Equilibrium Concentration of A)

Backward Reaction Rate Constant

Go Backward Reaction Rate Constant = Forward reaction rate constant/Equilibrium Constant

Forward Reaction Rate Constant

Go Forward reaction rate constant = Equilibrium Constant*Backward Reaction Rate Constant

Equilibrium Constant

Go Equilibrium Constant = Forward reaction rate constant/Backward Reaction Rate Constant

Number of Moles of Gaseous Reactants

Go Number of moles of reactants = Number of moles of products-Change in Number of Moles

Number of Moles of Gaseous Products

Go Number of moles of products = Change in Number of Moles+Number of moles of reactants

Change in Number of Moles

Go Change in Number of Moles = Number of moles of products-Number of moles of reactants

Backward Reaction Rate Constant Formula

Backward Reaction Rate Constant = Forward reaction rate constant/Equilibrium Constant
K_b = K_f/K_c

What is equilibrium law?

Equilibrium constant is the product of concentration of products at equilibrium by the product of concentration of reactants at equilibrium. This representation is known as equilibrium law or chemical equilibrium. The thermodynamically correct equilibrium constant expression relates the activities of all of the species present in the reaction.
