Question

If 30 g of reactant is used up in 15 seconds, calculate the mean rate of reaction in g.

Answer

2 g/s

Explanation

The correct answer is 2 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

Misunderstanding Concentration Effects

Students often think that increasing concentration has no effect on reaction rate.

To fix this, remember that increasing concentration usually increases the number of particles in a given volume, leading to more frequent collisions and a faster reaction rate.
