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 + B ----> C + D, two experiments were made. The first one using an initial concentration of A, [A]initial = 400 mmol/L, and an initial concentration of B, [B]initial = 0.4 mmol/L. The results of this first experiment were: Time (seconds) / 0 120 240 360 infinity Concentration of C, [C] / 0 2*10^4 ... click for more

Electrochemical cells

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)

Experiment

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 in different atoms. These exercises with static electricity highlight the electrons in some atoms. I. Balloon Interactions a.) Blow up two balloons and tie them up. b.) Place them next to each other on a table or solid surface. c.) Observe what happens. d.) Rub one of the balloons with the piece of fur in your electrostatic kit. e.) Place it next to the ... click for more
