Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is the formula to calculate the average rate of reaction?

πŸ’‘ Hint: Remember, Ξ”[R] refers to the change in concentration.

Question 2

Easy

Define what is meant by instantaneous rate.

πŸ’‘ Hint: Think of the graph's steepness at that point.

Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What is the average rate formula?

  • Rate = Ξ”[R]/Ξ”t
  • Rate = k[A]x[B]y
  • Rate = k

πŸ’‘ Hint: Focus on what represents change in concentration.

Question 2

True or False: Instantaneous rate can be found by measuring the time interval.

  • True
  • False

πŸ’‘ Hint: Think about how you calculate slopes from graphs.

Challenge Problems

Push your limits with challenges.

Question 1

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.

πŸ’‘ Hint: Focus on both numerical calculation and conceptual influence of temperature.

Question 2

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.

πŸ’‘ Hint: How does the presence of a catalyst influence reaction dynamics?
