The correct equilibrium expression would be one that has products over reactants, and to the power of their stoichiometric coefficient. Also, it would not include any liquids or solids.
The equilibrium expression for your balanced reaction is:
![\Large K_c = \sf{\frac{[SO_3]^2_{equil}}{[SO_2]^2_{equil}[O_2]^2_{equil}}](https://tex.z-dn.net/?f=%5CLarge%20K_c%20%3D%20%5Csf%7B%5Cfrac%7B%5BSO_3%5D%5E2_%7Bequil%7D%7D%7B%5BSO_2%5D%5E2_%7Bequil%7D%5BO_2%5D%5E2_%7Bequil%7D%7D)
The equilibrium expression for your balanced reaction is:
I would assume so.
Given
, we can simplify the fraction to 
Both would obtain the same proportions, so I don't see why putting a half cup of sugar would make things any different.
Hope this is the answer you are looking for.

Answer:
= 2.94 atm
Explanation:
The total pressure () in the container is given by:
The pressure of the oxygen () and the pressure of the helium (
) can be calculated using the ideal gas law:
<u>Where</u>:
V: is the volume = 25.0 L
n: is the number of moles of the gases
R: is the gas constant = 0.082 Latm/(Kmol)
T: is the temperature = 298 K
First, we need to find the number of moles of the oxygen and the helium:
Where m is the mass of the gas and M is the molar mass
And the number of moles of helium is:
Now, we can find the pressure of the oxygen and the pressure of the helium:
Finally, the total pressure in the container is:
Therefore, the total pressure in the container is 2.94 atm.
