Dynamic equilibrium Flashcards
1
Q
Reversible reaction
A
forward reaction as well as a backward reaction
2
Q
Forward reaction
A
reactants converted to products
3
Q
Backward reaction
A
products converted back to reactants
4
Q
Dynamic equilibrium
A
rate of forward reaction = rate of backward reaction
- constant interchange between products & reactants
- concentrations of reactants & products do not change
5
Q
Effect of concentration on dynamic equilibrium
A
- increase in concentration of reactant
- shift equilibrium position to the right
- forward reaction favoured
- more products formed
- increasing rate of reaction
6
Q
Effect of temperature on dynamic equilibrium
- exothermic reaction
A
- liberates heat
- increase in temperature would favour backward reaction
- low temperature must be used to favour forward reaction
- not too low so as to stop the reaction
7
Q
Effect of temperature on dynamic equilibrium
- endothermic reaction
A
- absorbs heat
- increase in temperature
- forward reaction favoured
- more products formed
- increase in rate of reaction
8
Q
Effect of pressure on dynamic equilibrium
A
- only gaseous reactions
- depends on number of moles of gaseous reactants & products shown in equation
