Equilibrium constant - ES Flashcards
1
Q
If aA + bB ⇌ cC + dD what is the expression of K꜀
A
K꜀ = [C]ᶜ[D]ᵈ/[A]ᵃ[B]ᵇ (products over reactants)
2
Q
Square brackets meaning in equilibrium constant
A
mean concentration
3
Q
What affects K꜀
A
the only things that changes K꜀ is temperature (K꜀ is a constant at a given temperature)
4
Q
K꜀ meaning
A
equilibrium constant
5
Q
K꜀>1 meaning
A
more products than reactants at equilibrium
6
Q
K꜀»1 meaning
A
greater than 10¹⁰ so equilibrium is far on the right and the reaction appears to have gone to competition
7
Q
K꜀<1 meaning
A
more reactants than products at equilibrium
8
Q
K꜀«1 meaning
A
less than 10⁻¹⁰ so equilibrium is far on the left and the reaction appears to have not happened
9
Q
K꜀ close to 1 meaning
A
equilibrium position is in the middle
