method of initial rates

Initial Rate Method - This method is used for reactions where more than one reactant species are involved. Initial rates of the reaction are determined by varying the concentration of only one reactant while keeping the concentrations of o..

This method is used for reactions where more than one reactant species are involved. Initial rates of the reaction are determined by varying the concentration of only one reactant while keeping the concentrations of other reactants constant. Initial ..

For reactions where many reactants are involved, the order of the reaction is determined by the method of isolation. This was developed by Ostwald. In this method, the concentrations of all the reactants except one are taken in excess. For e.g., in the reaction A + B + C + D Pro..

Methods to Determine Order of a Reaction - For determination of the order of a reaction, following methods are usually employed. a) Graphical Method b) Initial Rate Method c) Ostwald Method of Isolatio..

Choose the exponential function with the initial value as 6, increasing at a rate of 48% per year. => S( t ) = (1.48) t or S( t ) = 6(1.48) t or S( t ) = 6(0.48) t or S( t ) = 6(1.16) t..

Choose the exponential function with the initial value 13, decreasing at a rate of 0.42% per week. => S( t ) = 42(0.0013) t or S( t ) = 13(0.9958) t or S( t ) = 13(0.0042) t or S( t ) = 42(0.0995) t..

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 determined by drawing tangents to curve and then calculating their slopes. The reaction ..

The rate of a reaction is determined by measuring the concentration of the reactant or product at different intervals of time. The concentration is measured, by measuring a related property such as color, pressure or volume (as in the case of gas phase reactions), pH, optical rotation, el..

But for having unique value of the reaction rate (independent of the concentration term chosen), we divide the rate of the reaction, defined with respect to any of the reactants or products by the number of moles involved in the reaction. Thus, for the above reaction, rateh..

Jim deposited some amount in a bank at a rate of 3% compound interest. What was the amount deposited initially, if the balance in his account at the end of 5 years is found to be $3000? => $2826.35 or $2485.45 or $2686.45 or $2586.20..
