Question 1.
What is the formula to calculate the average rate of reaction?
Show hintHide hint
Remember, Δ[R] refers to the change in concentration.
Question 2.
Define what is meant by instantaneous rate.
Show hintHide hint
Think of the graph's steepness at that point.
3Question 3.
What is the average rate formula?
- Rate = Δ[R]/Δt
- Rate = k[A]x[B]y
- Rate = k
Show hintHide hint
Focus on what represents change in concentration.
4Question 4.
True or False: Instantaneous rate can be found by measuring the time interval.
- True
- False
Show hintHide hint
Think about how you calculate slopes from graphs.
Question 5.
A reaction initially has a concentration of 3M and decreases to 1M over 6 minutes. Determine the average rate of reaction and explain how altering temperature could influence this rate.
Show hintHide hint
Focus on both numerical calculation and conceptual influence of temperature.
Question 6.
Given a scenario where a catalyst is added, resulting in a reaction rate increase from 0.1M/min to 0.5M/min, calculate the factor by which the rate increased and discuss the implications of this in industrial applications.
