Measuring Rates of Reaction Flashcards
1
Q
What is the formula for measuring rates of reactions?
A
rate = amount of reactant used or amount of product
——————————————————————
time
2
Q
How can precipitation be used to measure the rate of reaction?
A
It clouds the solution, so the quicker the solution is no longer clear fully is the reaction time. It is subjective as people may disagree about the cloudiness.
3
Q
How is a change in mass used to measure reaction rate?
A
A gas is released so the weight changes, it is the most accurate method.
4
Q
How is the volume of gas given off used?
A
The more gas given off in a certain time interval means there is a faster reaction, this method is quite accurate.
