in which situation will the reaction rate increase? a when a catalyst is added b when the temperature drops c when the pressure is lowered d when the molecules are large and bulky
Answer
Brief Explanations:
催化剂能降低反应的活化能，加快反应速率；温度降低、压强降低会使反应速率减慢；分子大且体积庞大不利于分子间有效碰撞，会使反应速率减慢。
Answer:
A. when a catalyst is added
