The effect of a catalyst is to increase the speed of the reaction, this is the speed at which reactants, A and B, are consumed, ant the product, C, is produced.
Given that when C is produced the solution bubbles, the bubbles are an indication of progression of the reaction.
The greater the speed of reaction, the earlier the reaction will end and the earlier the bubbles will stop.
So the student can identify the catalyst because the bubbles will stop first.
Answer: <span>The test tube that stops bubbling first contains the catalyst.</span>
