Calculations Booklet and Equilibrium Flashcards
What is the formula for percentage yield
Actual yield/Theoretical yield *100
What is the formula for atom economy
Mass of desired product/Total Mass of reactants*100
What is molar volume
It is the volume occupied by 1 mole of gas
What is the formula of molar volume
Volume/number of moles
What is a dynamic equilibrium
It is when the concentration is constant and the rates of the forward and backwards reaction are the same
If there is more product than the reactant, the equilibrium position lies to which side?
To the right
Why would chemical companies be interested in altering the position of equilibrium
To ensure they make high yield of the product
When there is a TEMPERATURE INCREASE where does the equilibrium lie and what is the colour?
The right and the colour darkens
When there is a TEMPERATURE DECREASE where does the equilibrium lie and what is the colour?
The left and the colour becomes light
Increasing TEMPERATURE favours the?
ENDOTHERMIC REACTION
Decreasing TEMPERATURE favours the?
EXOTHERMIC REACTION
When there is a high pressure what happens?
The colour LIGHTENS and the equilibrium moves to the LEFT.
When there is a low pressure what happens
The colour DARKENS and the equilibrium moves to the RIGHT.
What happens when the pressure is INCREASED
It will favour the side with the LOWEST number of moles in the gaseous state
What happens when the pressure is DECREASED
It will favour the side with the HIGHEST number of moles in the gaseous state.
