Definition
The rate of reaction is the measure of how fast reactants can turn into products
The rate of reaction is the proportional to the increase in product concentration per unit time and the decrease in reactant concentration per unit time
Factors Affecting The Rate Of Reaction
Higher the temperature the faster the reaction
A higher concentration affects the rate of reaction as there will be high particle collision
A high pressure can effect the rate of reaction, as high pressure will result to faster collisions
Catalyst
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
Platinum and iron are examples of a catalyst as it helps in increasing a chemical reaction
Enzymes
Enzymes are protein molecules that act like catalyst in a biological body
Enzymes are proteins that act as biological catalysts, significantly speeding up chemical reactions within living organisms
What is the difference between a fast reaction and a spontaneous reaction?
Why does increasing the surface area of a reactant increase the rate of reaction?
Why do some reactions occur instantly, while others take hours or days?
What does the slope of a concentration vs. time graph represent in a rate of reaction experiment?
How can you determine the order of a reaction from experimental data?
