Finding the reaction order and rate constant.
I´ve wrestled with this all week, and I can´t seem to find a way to go from the product concentrations they give me to the reaction order. I´m out of ideas, so please help! I´m thinking about using a graphic solution, I´ve been using Excell to graph it but I still can´t figure it out. Here it goes: For the reaction A ...continues
Could you please show me how to do this, atleast the first one and let me know if there is anything tricky about the 2nd one if you decide not to complete that one. Thanks. (Complete problem found in attachment)

Static Electricity Exercises It is very difficult to visualize the submicroscopic particles that make up the atom. Atoms and the particles that make up atoms are much too small to be detected by ordinary microscopes. However, even though we cannot an atom we can see the effects from the interaction of the minuscule electrons ...continues
Ratio of rates from Arhenius equation
. Question : Two reactions have the same Arhenius frequency factor, while their energies of activation differ by 5020 Jmol-1. Calculate the ratio of their rate constants at 27degree Celsius
By electrolysis of water, 11.2L of oxygen at STP was prepared. A) what charge was required? B) If a current of 0.5A was used, how long did it take? Note: please explain step by step how to get each answer.
I would like help with the attached assignment except for question #4,#5,#6.
1 a) A copper refining cell is operating with an electrolyte which contains 0.05 m Sn2+. At what concentration of Cu2+ will the tin start to plate out in preference to the copper? The cell temperature is 40°C. b) A polarization potential arises from a concentration difference between ions in the ...continues
2 The following table gives some results from experiments in which the current efficiency of zinc deposition in an electrowinning operation was determined at various current densities (amperes per square meter of cathode surface area). The cathode area at the plant is 10,000 m2. Current Density C ...continues
3. Nickel is electrolytically refined at 40°C using an electrolyte containing 50 g/liter of nickel ion. The anodes contain copper impurities (< 2 wt.%) which may go into solution as the nickel anode dissolves. Calculate the concentration of Cu2+ ions in solution that is sufficient to result in the depos ...continues
