AI Thread Summary
The discussion revolves around determining the equilibrium state of a chemical reaction given specific conditions and a known equilibrium constant (K) of 0.0900 at 25 degrees Celsius for the reaction H2O(g) + Cl2O(g) <--> 2HOCl(g). Participants analyze three different sets of conditions to assess whether the system is at equilibrium or if it will shift towards products or reactants. For the first set of conditions (A), it is suggested that the reaction will shift towards the products due to an excess of gaseous reactants. In the second set (B), the minimal amount of Cl2O indicates that the equilibrium will shift to produce more reactants. The third set (C) is identified as being at equilibrium, as the calculated Kp equals the given Kc. The discussion emphasizes the importance of calculating K under different conditions to determine the system's state relative to the equilibrium constant.

I'm so confused about what to do for this problem... I know that I need to find K for the given conditions but I'm not quite sure how. Any help would be greatly appreciated

For each of the following sets of conditions, determine if the system is at equilibrium or not. For those not at equilibrium, state in which direction the system will shift.
It gives K as .0900 at 25 degrees Celsius for the reaction:
H2O(g) + Cl2O(g)<--> 2HOCl(g)
Then it gives several different conditions such as:
A) PH2O= 296 torr PCl2O= 15 torr PHOCl= 15 torr
B) 3.0 L flask contains .35 mol HOCl, .001 mol Cl2O and .98 mol H2O
C) 2.0 L flask contains .084 mol HOCl, .08 mol Cl2O and .98 mol H2O

A)

I believe the reaction will be towards the products because you have too many moles of gas on the left, so the reaction will work to react these gases and increase the product.

B)

There's very little ClO2 and so the equilibrium will be shifted to make more reactants.

C)

Equilibrium.
 
At any instant u have Kp = Kc

so calculate K for each given conditions And see whether it is equal to given K or not

U will have it in them ur book How to calculate the K in various conditions
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
