Module Question

A vial So2 (0.522mol.L) and O2 (0.633mol.L) react and reach equilibrium. Calculate the equilibrium concentrations of the products and reactants given that kc= 5.66 x 10^-10. Balanced Equation: 2so2 (g) + o2 (g) ----> 2so3 (g) For this problem i was able to do the icebox but i got stuck when i got x ...

Equilibrium value

I understand when they give you an initial amount of a product or reactant we can find the equilibrium by using the ice box method. But what happens when one of the values you obtain is greater than your initial. Would you just ignore it and use the other value?

Equilibrium Constant

After viewing the module there was a question that asked " If the equilibrium constant K is 61.0 for a given reaction, what is the value for the reverse reaction". How would I solve this? And what would I do if they had given us the equilibrium constant of a product instead?

Re: Thoughts after Test 1?

I definitely agree with Ben. The test overall was pretty straight forward but I feel like I did not pace myself very well. Before i knew it we only had ten minutes left and I still had 3 problems to work through. I think that for Exam 1 I'm going to start off by reading each question and answering t...

When frequency decreases why does the extent of the change in the electrical field decrease as well. We went over this in my discussion section but I'm still confused on why this occurs.

Re: Lecture on Friday 06/30/2017

If an electron moves from an energy level close to the nucleus it would lose energy and if it moves from an energy level far away from the nucleus, then it would gain energy. This means that the potential energy increases when the electron is farther away from the nucleus.
