Topic 5 - Measuring Rates of Reaction

Question 1

what is the equation for the rate of reaction?

Answer 1

rate of reaction = amount of reactant used up or amount of product formed / time

Question 2

how would you measure the rate of reaction for reactions that produce a precipitate?

Answer 2

1. mix the 2 solutions in a flask on a piece of paper with a mark on it
2. measure how long it takes for the mark to be obscured

Question 3

how would you measure the rate of reaction for reactions that produce a gas?

Answer 3

1. measure the lost mass by carrying out the reaction on a mass balance
2. use a gas syringe to measure the volume of gas given off
