Rates of Reaction - Coggle Diagram
Rates of Reaction
reversible reaction
a chemical reaction that goes both ways
⇌ symbol is used
forward reaction: goes to the right
Backward reaction: goes to the left
Factors affecting rate of reaction
Temperature
Pressure
Concentration
How changing the factors affect the equilibrium
Temperature
decrease
: The equilibrium is shifted to the exothermic reaction
increase
: Equilibrium is shifted to the endothermic reation
Concentration
decrease
: Equilibrium shifts to the side with a lower concentration
increase
: Equilibrium is shifted to the opposite side (less concentrated)
Pressure
increase
: The equilibrium is shifted to the side with less molecules
decrease
: The equilibrium is shifted to the side with more molecules
How changing those factors affected the rate of reaction
Temperature:
INCREASE: increases the frequency of
collisions and so increases the rate of reaction.
Pressure
INCREASE: increases the frequency of
collisions, making the collisions more energetic, so increases the rate of reaction.
Concentration:
INCREASE: increases the frequency of
collisions and so increases the rate of reaction.
