Hello, I'm unfortunately lacking any approach to this problem. How do I combine both equilibria to achieve the required OH concentration? One idea would have been to first solve for the maximum OH concentration for solubility, but what's the connection to complex formation then? Thank you for any answers.
Hello, I only have what is written below, but I did not understand it 100% and would need an explanation to the questions What is the equilibrium reaction in relation to the calcium cycle? CaCO3 + H2CO3 <=> Ca2+ + HCO -3 , exothermic What and why is balanced here and is there an imbalance/equilibrium?…
Hey, this is the formula of the law of mass action: But how would I change this to C, D, A and B? Thank you.
Could someone please help me with the following task? To produce sulfuric acid, sulfur dioxide (c0 = 8 mol/L) is oxidized with oxygen (c0 = 5 mol/L) at 726 °C to sulfur trioxide. At equilibrium, the concentration of sulfur trioxide is 7.56 mol/L. Calculate the equilibrium constant Kc for the reaction. Thanks in advance!
Good day, You calculate the equilibrium constant Kc, for example? A + B -> C + D and C + D -> A + B Now you use the concentrations at equilibrium to establish the MWG and to determine Kc, i.e. to say on which side the equilibrium lies. Now there are more products when…
I don't understand how to calculate all of this, since we never discussed it in class. Can someone please give me a starting point for calculating it?
Example: The unused hydrocarbons are oxidized to water vapor and carbon dioxide. Is this sentence correct: Increasing temperature promotes exothermic reaction or should the sentence be different?
Above is my teacher's solution. However, I don't quite understand how the conversion from (mol*L^-1)^2/(mol*L^-1)^4 to L^/mol^2 worked. When I convert it (red in the image), I get a different result. I generally have trouble combining units when there are multiple fractions (here, the -1 is a power).
Hello, I need help with b, can someone please help me?
Hello, How would you solve the following problem? (Please provide your calculation method) At a certain temperature, the two gases nitrogen and oxygen react with each other to form nitrogen monoxide. The initial concentration of the reactants is 1 mol/L each, and the equilibrium constant Kc for this synthesis is 1.1-10^-2? Calculate the equilibrium concentrations…
