Question
A reaction produces 50 g of product in 10 seconds. Calculate the mean rate of reaction in g.
Answer
5 g/s
Explanation
The correct answer is 5 g/s. This is correct because it matches the rate of reaction, reversible reaction, equilibrium, catalyst, or Le Chatelier concept tested by this approved Chemistry 8462 learning objective. The other options are incorrect because they change the quantity, unit, condition, graph interpretation, or chemical relationship in the question.
Common mistake
Confusing Rate Calculation
Students often confuse the calculation of rate by using the wrong quantity (e.g., using mass instead of gas volume or vice versa).
Ensure to identify whether you are measuring the change in mass or gas volume and use the appropriate quantity in your rate calculation.
