4a.jpg 4a2.jpg So I was able to do part A for this problem but when it came to part B I did not know exactly what to do to find the rate limiting step and I am dear need of help on this. I don't know if I am overthinking this or not but I need clarification on what steps to take. Q4 B: "Which ...

So does this mean that overall rate of a reaction is given in mol.L -1 .s -1 and the rate constant K will depend on the given concentration to cancel out units and obtain the rate given in a problem? Or is it more so just dependent on the order of the reaction and the rate law used? I am still confu...

I have seen that when it comes to cell diagrams the elements in the same states (aq,l, g, etc) are not separated by a single line but by a comma. but what happens when you get multiple states on the anode side or cathode side? If there are three states such as solid, liquid, and gas, is there a spec...

I have been doing problems for electrochemistry and I am having difficulty knowing which of the redox reactions to name as the cathode or anode. Could someone please provide me with the reasoning behind how to identify which element as cathode or anode??

I had trouble starting this problem: "Determine the reaction enthalpy for the hydrogenation of ethyne to ethane,from the following data: C_{2}H_{2 }(g)+ 2H_{2}(g)\rightarrow[tex]\Delta H_{c}^{\circ}( C_{2}H_{2 }(g))=-1300 kJ.mol^{-1}, \Delta H_{c}^{\circ}( C_...

Why is it that despite the fact that Transition Metal Cations in solutions form complexes with H2O but when you add thing such as NH3 or KCN or NaCl that they replace the H2O Ligands? Shouldn't the fact that H2O has two pairs of electrons that H2O would be more electron rich than NH3, HCN, or NaCl a...

How can you determine polarity based off of the shape of a compound? I could not understand exactly why Phosphorus trichloride was polar and not nonpolar when I encountered it on one of the practice midterms.

How do Ionization Energy and Electron Affinity affect Electronegativity? I also don't understand electronegativity trend over the Periodic Table. Does it follow the same trend that ionization energy follows on the periodic table?

I was reading the section on Schrodinger's equation for wavelength function calculation and found some confusing concepts about it. Why is it that in the Schrodinger equation Kinetic energy is negative in value for calculating wavelength function? Why is the wavelength function's simple form decepti...

I had little experience with Limiting Reactant Calculations in High School since a lot of this material was not covered in my High School classes. I do not know how to set up and solve for products from limiting reactants and would like a simplified explanation of the steps to go about the mathemati...
