  • How Much?
    • Empirical formula
      • Way of finding out formula for compound
      • 1. List elements      2. write experimental masses or percentage 3. divide each mass or percentage by the Ar    4. turn into ratio in simplest form
    • Moles
      • Number of moles= mass in g / Mr (relative formula mass)
    • Percentage yield
      • = actual yield in g / predicted yield in g x 100
    • Rates of reaction
      • amount of reactant used or product formed / time
      • What affects it
        • Temperature
          • Force and frequency of collisions
            • Activation energy
            • concentration/ pressure
        • concentration/ pressure
        • Catalyst
        • Activation energy
    • Reversible reactions
