1. What is the rate of a chemical reaction?

Change in concentration over time · Change in temperature over time · Change in pressure over time · Change in volume over time

2. Which factor does NOT affect the rate of a chemical reaction?

Concentration of reactants · Temperature · Nature of reactants · Color of reactants

3. What is the unit of the rate constant for a first-order reaction?

mol L^-1 s^-1 · s^-1 · L^2 mol^-2 s^-1 · mol L^-1

4. What is the effect of increasing temperature on the rate of reaction?

Decreases the rate · Increases the rate · No effect · Halves the rate

5. In a zero-order reaction, the rate of reaction is independent of:

Concentration of reactants · Temperature · Catalysts · Pressure
