Q&A
Atom economy - CORRECT ANSWER (Molecular mass of desired products/ Molecular
mass of all products) x 100
Hess's Law - CORRECT ANSWER The energy change of a reaction from reactants to
products is equal regardless of route taken
Haber process equation - CORRECT ANSWER N2 + 3H2 = 2NH3
Haber process conditions - CORRECT ANSWER 450 degrees, 200 atm, iron catalyst
partial pressure - CORRECT ANSWER Mole fraction x total pressure
Mole fraction - CORRECT ANSWER Mole of element / molecule
