Question
If 30 cm³ of gas is produced in 15 seconds during a reaction, calculate the mean rate of reaction in cm³/s.
Answer
2 c³/s
Explanation
The correct answer is 2 c³/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
Incorrect Units for Rate of Reaction
Students often use incorrect units when calculating the rate of reaction, such as using grams instead of g.
Always ensure to express the rate of reaction in the correct units, such as g, c, or mol/s, depending on the context of the calculation.
