Atom economy comparison
Green chemistry: compare atom economy and E-factor for different routes to a product.
Open the interactive simulation →How to use this simulation
- Choose a process, or type your own equation and the desired product.
- Read the atom economy.
- Enter the masses of inputs and product to calculate the E-factor.
- Compare the routes.
What to notice
- Atom economy = mass of desired product ÷ total mass of reactants × 100.
- Addition reactions can reach 100%; substitutions always waste some atoms.
