. Average rate of a reaction does not represent the actual rate of a reaction at any instant of time. From the figures 6.1 and 6.2 it is clear that the rate of reaction actually decreases with time. This is because the rate of reaction depends on the concentr..

Concentration dependence of rate is a differential equation (equation 8). It is tedious to determine the instantaneous rates from the slopes of the tangents for each value of t and this in turn makes the rate law determination difficult. To avoid this difficu..
Experimental Determination of Rate of Reaction
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 rate and instantaneous ..
Rate of Chemical Reactions
Everyday experience tells us that chemical reactions take place in widely varying rates. Infact rates of various reactions vary from very slow to very fast. Some reactions are so rapid that they occur as soon as the reactants are mixed. For example, the reactions involving ioni..

very helpful of a complex problem, oh my god I would have never completed this problem with out the tutor. Tutor vista thank u so much.
My daughter use to study from personal tutor for Maths, but now when she is studying through TutorVista, she gets tutoring for Maths, Science, English.. everything at a price cheaper than the Math tutor she had.
Looking for More Help!
