Rates of Reaction Flashcards
Define’the rate of chemical reaction’
How fast the reactants are changed into products
Rate of reaction in graphs
The steeper the line on the graph, the faster the rate of reaction.
The quickest reactions have the steepest lines and become flat in the least time
State 5 factors affecting the rate of reaction
Concentrations of reactants
Pressure of gasses (volume)
Surface area
Temperature
Catalysts
How is rate of reaction calculated
rate of reaction=amount of reactant used or product formed/Time
rate it reaction (mol/s)= Moles of reactant used or product formed/time
Name three common ways of measuring rate of reaction
Loss in mass of reactants
Volume of gas produced
Time for a solution to become opaque
What is collision theory
Chemical reactions can only occur when reacting particles collide with each other with sufficient energy
