Basic physics. Work/energy and force are different fundamental physical concepts. Knowing the force at _some_ point of the bond breaking process is not enough to say how much work needs to be done to achieve separation.

In any case, I don't know what a lambda factor is, I don't know what the selected equilibrium reaction is, and I don't have the basic thermodynamic information to hand. Is this information that is provided in the question paper but you are withholding from us? How do you expect anyone to solve this problem?

Hello everyone,
I am posting this message because I have an exercise to do and I am completely lost. Could you help me on how to do it? :

Exercise:
Consider the combustion of methane with regular air. Inlet temperatures of methane and air are 300 K and 400 K, respectively. The mass flow rate of air is 0.1 kg/s, and the lambda factor is 0.9.
This is a case of a rich mixture (λ<1). In this case, the species in the products will contain CO2, H2O, CO, H2, and N2, among other species. Mass (or atoms) conservation is not enough to close the problem.

1) Considering only the five species in the products mentioned above, evaluate the Kp of the selected equilibrium reaction based on the basic thermodynamic information (enthalpies of formation, molar heats and reference entropy of the species involved).

2) Evaluate the concentration of the five species considering Tcc=1400 K

3) Evaluate the combustion temperature and the concentration of the five species (global itetaive process)

Thank you for your help. This exercise is very important to me.

Any acidic compound react with carbonates to CO2, what will blow up your bags.

Check your compounds, if they are acidic.  Normal salts are neutral. But minerals maybe not.

Howdy, fellers and ladies!

I am at a loss on the explosive reaction I have been creating and am seeking prof help.

I have been creating sparkling water for the fam for many years and have, in the last 2 years, starting to add minerals back in for flavor and health.  I use reverse osmosis as my starting point and run a custom kegerator set up.

Anyway, my question is regarding the minerals I use appear to 'explode' when mixed together and vacuum packed for later use.

I source high quality lab / food grade USA sourced (when possible).  Here is my list:

Real Salt (Redmond Life)
Potassium Bicarbonate
Epsom salt (aka magnesium sulfate)
Gypsum (aka calcium sulfate)
magnesium carbonate
Calcium Carbonate
Baking Soda (Sodium bicarbonate)
Ascorbic Acid

After the first large batch of this (enough for 20 kegs bc I dont want to mix every single keg we do) I noticed the vacuum packs I did of dry powder expanding big time.

I used what I could and removed the Vitamin C on the next batch  as it clearly had a reaction.  Then I removed the baking soda on the next batch.  I add these two in manually each time to each keg.

Still with those two removed, I made a batch last night, an explosion of powder was what I found.

I would think this is probably some basic high school chemistry that I am just not walking around with.... please let me know/explain what is happening here.
