to reactants
--scene one is equilibrium (d/c^2 and 5/3^2 means the Kc is 0.55) and scene 2 is 2/3
how??
0.25
you just had to inverse and square it
to reactants
Kp was given, but the others are in mol so we need to convert Kp to Kc or use PV=nRT to
get pressure of the equation
New Kc will be 2.5 and you get 2.78 for Q and it moves to the reactant
Q>K, the reaction will proceed to the left
Standard state is 1 mol, 1 atm, 273K
(1)^2/1 and K is .15, so it goes left!
only III
K=1 means it isn’t product or reactant favored
At K=100 you couldn’t say completion (maybe to the 8 or 9 power)
At 100 K=1 and at 500 K=100, so there is more product favored and y
produced at 100
FRIDAY 5/17
