Key Questions:

1. How does increasing the surface area to volume ration of a solid reactant affect the rate of a chemical reaction?
   • Increasing the surface area to volume ratio will increase the rate of the chemical reaction because the there will be more contact between the reactant Particles. Increasing the frequency of successful collisions.
2. How does increasing the concentration of reactants in reacting gases, and the surface solution, the pressure of area of solid reactants increase the rate of a chemical reaction?
   • Increasing the concentration of reactants in solution, the pressure of reacting gases, and the surface area of solid reactants increases the frequency of collisions and so increases the rate of reaction.
3. How does increasing the concentration of reactants in solution affect the rate of chemical reactions?
   • Increasing the concentration of reactants in solution increases the rate of chemical reactions.
4. How does changing the concentration of a reactant from 1M to 2M affect the rate of a chemical reaction?
   • When the reactant concentration is 2M there are twice as many Particles to react. This means the time it would take for the same number of successful collisions will half.
5. How does increasing the concentration of a solution reactant or the pressure of a gas reactant affect the rate of a chemical reaction?
   • Increasing the concentration of a solution reactant or the pressure of a gas reactant will increase the rate of a chemical reaction because there would a higher number of Particles in the same area, therefore successful collisions between reactants Particles will be more frequent, increasing the rate of reaction.
6. How does increasing the surface area of solid reactants affect the rate of a chemical reaction?
   • Increasing the surface area of solid reactants will increase the rate of a chemical reaction.
