Chemical Equilibria Flashcards
(11 cards)
What is happening in at equilibrium in a reversible reaction
Forward and reverse reactions proceed at equal rates
The concentrations of reactants and products remain constant
What is Le Chateliers principle
Why, when a reversible reaction is used in an industrial process, a compromised temperature and pressure may be used
Why does a catalyst not affect the position of equilibrium
What is the effect of a temperature change on the position of equilibrium
What is the effect of a pressure change on the position of equilibirum
What is the effect of changing concentration on the position of equilibrium
What is the expression for Kc
The concentration of the products to the power of their moles over the concentrations of the reactants to the power of their moles
How do you find the units for Kc
You take the equation for Kc and substitute each concentration with moldm^-3 and then cancel out until you have an answer
How do you interpret Kc
What is Hess’ Law
