Graphical Method of Order Determination
Graphical Method of Order Determination - First, the data of concentrations versus time is obtained by a suitable method. Then, the data is plotted as concentration versus time. From the resulting plot, the instantaneous rates are det..
Order of a Reaction
The order of reaction is determined with respect to each reactant in the reaction. The order of a reaction is the power to which the concentration of a reactant is raised. This is the order with respect to one reactant only..

For this reaction, the increase in the concentration of acetic acid is determined by measuring the pH of the solution (sample). The concentration values obtained at different times are then plotted. From the graph of concentration versus time, the average rat..
Fractional Order Reaction or Complex Order
Fractional Order Reaction or Complex Order - Example 7: Hydrogen (H 2 ) gas reacts with bromine (Br 2 ) gas to give hydrogen bromide vapor. The chemical reaction is represented by the equation as follow..

For a reaction A + B C + D. The rate law for the reaction is expressed as rate = k [A] m [B] n If the concentration of B is kept large, then [B] essentially does not change over time and if the rate of reaction is determined as rate = k [A] then this rea..

>Simple reactions are those, which involve a single elementary reaction. The rate law can be written from the stoichiometry of the chemical equation. One such reaction is the gas phase reaction of ozone (O 3 ) with nitric oxide (NO). This bimolecular rea..
Half Life of a Reaction
Only for the first order reaction t 1 / 2 is independent of the initial concentration of the reactant. This relation can be used to determine the order of a reactio..

Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
Tutor Vista tutors actually helped me to think through some of the problems instead of just doing them for me.Now i am more confident with math ,Thank you all
Looking for More Help!
