how rates of reactions are measured Flashcards
3 ways to measure rates of reaction
measuring mass, the disapearing cross, collecting the gas
how does collecting gas work
hydrogen gas is one of the products released when dilute hydrochloric acid reacts with zinc metal.
By collecting the hydrogen gas that is produced over water or in a syringe, rate graphs can be produced. The volume of gas produced and the time taken need to be recorded.
how does measuing mass work
the mass of the apparatus can be monitored and recorded at time intervals throughout the reaction. As hydrogen bubbles escape, the apparatus will lose mass.
what can be used to record the rates of reaction
graphs can be used to follow the course of a reaction. A graph can tell us many things about a reaction
how can a rate of reaction be measured
by measuring the amount of product formed in a certain period of time
