Probability and Equilibrium
Cards in this deck (14)
- 1probabilityways of x / ways total
- 2AND - probability(multiplies)
- 3OR - probability(adds)
- 4AND & OR - probability(combination) example: probability of rolling an 8 using two standard six-sided dice
- 5NOT - probability(1 - Px) example: probability of NOT drawing two hearts off the top of a standard deck of 52 cards using two different methods
- 6distributionone way that things (atoms, energy) can be allocated
- 7most probable distribution (MPD)can be calculated using AND and OR probability rules
- 8relative probabilitiesprobabilities of various distributions/probability of the most probable one (relatively probability of the MPD = 1)
- 9equilibriumdynamic fluctuation around the most probable distribution
- 10Le Châtelier's PrincipleIf a system at equilibrium is disturbed, a reaction will occur which will reduce (but not eliminate) that disturbance and create a new, shifted equilibrium
- 11steps for calculating the amounts of different molecules present at equilibrium1) Determine the number of moles of each of the exchanging atom types
2) Add these to get the total number of exchanging atoms
3) Determine the probability of a randomly selected atom being of each type
4) Determine the approximate probability of each molecule type
5) Determine the total number of molecules
6) Determine the number of each type of molecule at equilibrium - 12The Law of Large NumbersAt the mole scale, the MPD is much more likely than any other, and fluctuations that occur are beyond the limits of measurement
- 13Keq and ICEGiven a Keq value, find the MPD by...
1) Initial: stating initial amounts of each molecule
2) Change: writing change with variables that are based on molar coefficients (and direction of reaction)
3) Equilibrium: subtracting change from initial and inputting expressions into Keq format - 14steps for calculating the amounts of different molecules present at equilibrium after a disturbance1) State the initial molar amounts, stress, and prediction for effect of stress
2) Calculate the new total number of atoms
3) Determine the probability of a randomly selected atom being of each type
4) Determine the number of each type of molecule at equilibrium
