Unit 3 Flashcards
Equation for percentage yield
(actual/ theoretical)x 100
Equation for molar volume
n=v/mV
Equation for atom economy
(gfm of desired product/ gfm of all reactants) x100
The concept of equilibrium is applied to
reversible reactions
A chemical reaction is in a state of equilibrium when
the rate of the forward reaction is equal to the rate of the reverse reaction
Equilibrium- What happens as a result of A or B being increased
the original equilibrium will be upset and more C and D will be produced until a new equilibrium is established
If adding reactants then equilibrium shifts to the
right
If adding reactants then equilibrium favours the
products
Equilibrium- What happens as a result of C or D being removed as it was produced
shifts to the right, making more c and d and favouring the products
Equilibrium- What happens as a result of C or D being increased
shifts to the left
Equilibrium- What happens as a result of A or B being decreased
shifts to the left
What effect does a catalyst have on an equilibrium reaction
No effect on the position of equilibrium but it can alter how quickly equilibrium can be reached
