difference between reaction of 1st order and 2nd order.

. It can be a fraction and negative too (reactions with negative order will not be discussed here). Various reactions display different orders. A few examples are liste..

Calculation of Order of a Reaction from t 1/2 Values - A reaction is carried out at two different initial concentrations of a reactant [A], that is [A] 0 , 1 and [A] 0 , 2 and the respective t 1 / 2 values (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 rate so obta..

Reaction Quotient and the Equilibrium Constant - The concentration ratio, i.e., the ratio of the product of concentration of the products to that of the reactants at any time (t) is known as the concentration quotient 'Q' of the reaction at time (t). The value of Q c or Q p will..

From the E values of the two electrodes one can find out whether a given redox reaction is feasible or not. A redox reaction is feasible only if the species which has higher potential is reduced i.e., accepts the electrons and the species which has lower reduction potential is ..

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 difficulty, the integrated form of the rate law..

.e., its reaction is fast and more exothermic. This also implies that the reverse reaction becomes more difficult i.e., the more reactive a metal, the more difficult it is to extract from its ore. The metal is also more susceptible to corrosion with oxygen and water. The reactiv..

Isolation Method - 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 t..
