Extent of Reaction

Extent of Reaction measures the progress of a reaction and is defined as the degree to which a reaction has advanced.

Symbol: ξ_Reaction

Measurement: Amount of SubstanceUnit: mol

Note: Value should be greater than 0.

Formulas to find Extent of Reaction

Other formulas in Basic Formulas category

Go Extent of Reaction given Change in Number of Moles

ξ Reaction = (\frac{Δn}{v i})

Go Extent of Reaction given Number of Moles Initially and at Equilibrium

ξ Reaction = (\frac{n Equilibrium - n initial}{v i})

Go Number of Moles Initially given Extent of Reaction

n initial = (n Equilibrium - (v i \cdot ξ Reaction))

Go Number of Moles at Equilibrium given Extent of Reaction

n Equilibrium = n initial + (v i \cdot ξ Reaction)
