Determine if the factors listed below will increase or decrease the rate of a chemical reaction. Column A 1. Decrease the temperature: Decrease the temperature 2. Add a catalyst: Add a catalyst 3. Decrease the concentration of reactants: Decrease the concentration of reactants 4. Crush a solid reactant into a powder: Crush a solid reactant into a powder Column B a.Increase the reaction rate b.Decrease the reaction rate
Based on the information provided:
1. Decrease the temperature: Decrease the reaction rate
2. Add a catalyst: Increase the reaction rate
3. Decrease the concentration of reactants: Decrease the reaction rate
4. Crush a solid reactant into a powder: Increase the reaction rate
So the correspondence between Column A and Column B is:
1. Decrease the temperature: Decrease the reaction rate (b)
2. Add a catalyst: Increase the reaction rate (a)
3. Decrease the concentration of reactants: Decrease the reaction rate (b)
4. Crush a solid reactant into a powder: Increase the reaction rate (a)
