Change in Number of Moles Solution

STEP 0: Pre-Calculation Summary
Formula Used
Change in Number of Moles = Number of moles of products-Number of moles of reactants
Δn = nP-nR
This formula uses 3 Variables
Variables Used
Change in Number of Moles - (Measured in Mole) - Change in Number of Moles is the difference of moles of products and reactants.
Number of moles of products - (Measured in Mole) - Number of moles of products is the the moles which are present in gaseous state of the products in a reaction.
Number of moles of reactants - (Measured in Mole) - Number of moles of reactants is the the moles which are present in gaseous state of the reactants in a reaction.
STEP 1: Convert Input(s) to Base Unit
Number of moles of products: 15 Mole --> 15 Mole No Conversion Required
Number of moles of reactants: 5 Mole --> 5 Mole No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Δn = nP-nR --> 15-5
Evaluating ... ...
Δn = 10
STEP 3: Convert Result to Output's Unit
10 Mole --> No Conversion Required
FINAL ANSWER
10 Mole <-- Change in Number of Moles

12 Equilibrium Constant Calculators

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 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))
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 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)
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

Change in Number of Moles Formula

Change in Number of Moles = Number of moles of products-Number of moles of reactants
Δn = nP-nR

What is equilibrium constant?

Equilibrium constant is defined as 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.
