Calculating Rates Of Reaction Flashcards
1
Q
Calculating rate of reaction
A
Rate = Quantity of reactant used OR product formed / time taken
2
Q
Calculating rate with mass
A
Rate (g/s) = change in mass (g) / time (s)
3
Q
Calculating rate with volume
A
Rate (cm^3/s) = volume of gas (cm^3) / time taken (s)
4
Q
When would we use a gas syringe to measure volume?
A
When we want to measure the volume of a soluble gas as the normal method would result in the gas dissolving in the water, resulting in not all volume being measured and inaccurate results. However, gas syringes can be prone to leakage
5
Q
Calculating rate with colour change
A
Rate = 1 / time (s)
OR
Colourimeter
