In this approach, you analyze initial rate data by fixing the concentration of all but one species, say X. Next, the rate law equation is linearized through a logarithmic transformation and a least-squares analysis is used to obtain a and its standard devaition. The process is repeated by keeping (X) constant and varying [Y] to obtain b and its standard deviation. Finally, using a and b, the average value of k and its standard deviation are deduced. a +/- b = +/- || +/- Reaction order k +/-

. Account for the increase in reaction rate brought about by a catalyst.
Consider the following statements: In general, the rate of a chemical reaction increases a bit at first because it takes a while for the reaction to get warmed up. After that, however, the rate of the reaction decreases because its rate is dependent on the concentrations of the reactants, and these are decreasing. Indicate everything that is correct in these statements, and indicate everything that is incorrect. Correct the incorrect statements and explain.
A reaction is started by mixing reactants. As time passes, the rate decreases. Explain this behavior that is characteristic of most reactions.
