Rate of reaction
Question
- A. Correct safety-context: Use units such as g/s, cm3/s or mol/s for rate of reaction calculations. within Calculating rates of reactions
- B. Distractor safety-context A: confuses this with a different Rate of reaction idea
- C. Distractor safety-context B: uses the right words but gives the wrong cause or condition
- D. Distractor safety-context C: answers a neighbouring objective instead of Calculating rates of reactions
Answer
The answer is Correct safety-context: Use units such as g/s, cm3/s or mol/s for rate of reaction calculations. within Calculating rates of reactions.
Explanation
The correct option is "Correct safety-context: Use units such as g/s, cm3/s or mol/s for rate of reaction calculations. within Calculating rates of reactions" because it directly matches the learning objective in Calculating rates of reactions. The other options are wrong because they either switch to a neighbouring Rate of reaction idea, reverse the chemistry relationship, or describe a condition that does not answer this objective.
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.
