xi=min(n1/nu1,n2/nu2)

What you provide

What you provide

  • First reactant amount expressed in mol, using the same scenario as the other inputs
  • First coefficient, using the same scenario as the other inputs
  • Second reactant amount expressed in mol, using the same scenario as the other inputs
  • Second coefficient, using the same scenario as the other inputs

What you receive

What you receive

  • Maximum reaction extent in mol reaction from the stated equation
  • A symbolic formula plus substituted working with your values
  • Visible assumptions, field guidance, and an authoritative learning reference

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

This calculation is not a laboratory procedure; verify purity, units, hazards, activities, and conditions.

Use internally consistent units and retain extra precision when carrying the result into another calculation.
