Formula breakdown

Formula

rate₁ ÷ rate₂ = √(M₂ ÷ M₁)

= 3.984095364448

Note

Simplified model: these results assume ideal behaviour (ideal gases, dilute solutions, complete reactions) and standard textbook constants. Real laboratory values vary with temperature, pressure, purity and activity coefficients. Do not rely on this for safety-critical or analytical work.
