Kp Flashcards
What is the significance of Kp>1?
-means we are going to have more of the products then reaction at equilibrium
What haps to rp at a constant temperature?
It’s constant
How does equilibrium respond if the reactants or products are doubled?
- So if reactants or products double equilibrium will respond and double the opposite (reactants or products)
What is the effect of an increase in temperate on kp?
- Increase in temperature causes the equilibrium to move to the endothermic side of the equation.
-then the moles of the product decrease and the moles of the reactants increase which causes the value of KP to decrease.
What is the total pressure of systems equal to?
Sum of the partial pressures
What are the units for kp?
Kpa
How do you calculate KP when you’re missing the partial pressure of either the reactant or product?
You add all the partial pressures that you’re given together and take away from the total partial pressure which will give you the missing partial pressure
What is the relationship between the partial pressure and the mole fraction?
Partial pressure is directly proportional to the mole fraction
How do you calculate the mole fractions from a KP question?
-You find the total moles first, which is done by adding all the moles in the equation together
-Then you divide the individual moles of the products and reactants by the total moles
What is the sum of mole fractions supposed to add up to?
1
How do you work out the partial pressure using more fractions and total pressure?
= mole fractions X total pressure
