#1
Front (Question)

Key features of a dynamic equilibrium

Back (Answer)

• Rate of forwards reaction = rate of backwards reaction • Concentration of reactants and products is constant

#2
Front (Question)

If an equilibrium lies to the left, what has a higher concentration at equilibrium? Reactants OR products

Back (Answer)

Reactants

#3
Front (Question)

If an equilibrium lies to the right, what has a higher concentration at equilibrium? Reactants OR products

Back (Answer)

Products

#4
Front (Question)

Le Chatelier’s Principle

Back (Answer)

If a closed system in dynamic equilibrium is subjected to a change, the position of equilibrium will move in the direction that opposes that change

#5
Front (Question)

Conditions for the Haber process

Back (Answer)

• 200atm • 400-450°C • Iron catalyst

#6
Front (Question)

Kc

Back (Answer)

• Equilibrium constant (in terms of concentrations) • Shows the composition of a mixture at equilibrium

#7
Front (Question)

Kc equation

Back (Answer)

Kc = ([P1]ᵖ¹[P2]ᵖ²) / ([R1]ʳ¹[R2]ʳ²) [R] - reactant conc [P] - product conc r and p - stoichiometric coefficients

#8
Front (Question)

What variable can alter Kc?

Back (Answer)

Temperature

#9
Front (Question)

Concentrations if: Kc «_space;1

Back (Answer)

[Reactants] > [Products] (Equilibrium to the left)

#10
Front (Question)

Concentrations if: Kc»_space; 1

Back (Answer)

[Products] > [Reactants] (Equilibrium to the right)
