Chemical Equilibrium Flashcards
Which reaction is favored with increased/decreased pressure
Increased pressure = reaction with fewer moles
Decreased pressure = reaction with more moles
Which reaction is favored with increased/decreased temperature
Increased temp = endothermic favored
Decreased temp = exothermic favored
Which reaction is favored with increased/decreased concentration of reactant
Increased concentration of reactant = forward
Decreased concentration of reactant = reverse
Which reaction is favored with increased/decreased concentration of product
Increased concentration of product = reverse
Decreased concentration of product = forward
Temperature change vs Kc:
Endothermic
Temp increase = Kc increase
Temp decrease = Kc decrease
Temperature change vs Kc:
Exothermic
Temp increase = Kc decrease
Temp decrease = Kc increase
Rate of reaction vs time graphs:
How do we know which reaction is which line
The reaction that is being initially favored, initially has a higher reaction rate and then it decreases while the other reaction not being favored rises
