Reaction Rates Flashcards
How does increasing conc affect rate
Particles are closer together so collide more leading to more successful collisions
How do temp increases increase rate
Combination of more collisions and more energetic collisions means a small increase in temp can cause a large increase in rate
What is a homogenous catalyst
A catalyst that is in the same phase / state as the reactant
What is a heterogenous catalyst
A catalyst that is in a different state or phase as the reactant
What happens to a Boltzmann distribution curve with temp increase
Peak is lower and moves to the right
What is the definition of rate of reaction
The change of conc/ amount of a reactant or product per unit time
What is the definition of rate of reaction
The change of conc/ amount of a reactant or product per unit time
What does the area under the curve in a Boltzmann graph show
The total number of molecules
What is the collision theory
For a reaction to occur particles must collide in the right direction with a minimum amount of kinetic energy
What is the collision theory
For a reaction to occur particles must collide in the right direction with a minimum amount of kinetic energy
What is total pressure
Sum of all the pressures of the individual gasses
What is a mole fraction
Proportion of gas in a gas mixture
How is partial pressure calculated
Mole fraction of gas X total pressure in mixture
