Answer
Increasingconcentration
Explanation
The correct answer is Increasingconcentration. This answer directly addresses the question: Which factor is likely to increase the rate of a reaction involving gases? It matches the approved Chemistry 8462 learning objective and the linked subtopic. The other options are incorrect because they either change the rate, catalyst, reversible reaction, equilibrium, or graph context, or they do not answer the exact point being tested.
Common mistake
Misinterpreting Graphs
Students often misinterpret the steepness of a graph, thinking a steeper graph indicates a slower reaction rate.
Remember that a steeper graph gradient actually indicates a faster reaction rate. Always link the gradient to the rate of reaction.
