1
Q
what is the Equilibrium constant
A
a value of the ratio between the concentration of the ractants and the concentration of the products
2
Q
how do we represent concentration
A
we use [ ] square brackets to
indicate the concentration
3
Q
what is the Kc equation
A
Kc = [products] / [reactants]
4
Q
if there are coefficients. we display them as ___ in the KC equation
A
powers
5
Q
what is concentration measured in
A
mol dm^-3
6
Q
how do you find out the units for Kc
A
place mol dm-3 in the brackets, do any powers, then simplify
7
Q
what does Kc tell you about equilibria
A
large value of Kc - equilibrium lies to the right
small value of Kc - equilibrium lies to the left
chemistry - Equilibria
