determination of concentration quotient of chemical 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 r..

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 be differe..

Rates of chemical reaction depends on the inherent characteristics or nature of the reactants. That is the reason, why some reactions are fast while others are slow. For E.g., oxidation of ferrous ion by KMNO 4 (potassium permanganate) in acidic medium is fast, while t..

Consider a reversible reaction expressed by the following general equation: where A and B are two substances which react to form new substances C and D and C and D react under the same conditions forming the original substances A and B. Let us assume that the concentrations of t..

Rate of a Reaction - Rate of reaction basically means the speed at which a chemical reaction occurs. The speed of a reaction is determined by monitoring the concentrations of the reactants or products at intervals of time. The vo..

Increasing the concentration of one of the reactants or decreasing the concentration of one of the products shifts the equilibrium in favor of the products. On the other hand, decreasing the concentration of one of the reactants or increasing the concentration..

Conclusion - The rate of a reaction is measured in terms of change in concentration of a reactant or a product with time. Rate of a reaction is measured by following the concentration changes either by chemical analysis or by observing some other pr..

Half life of a reaction is defined as the time required for reducing the concentration of a reactant to half its initial value. It is denoted as t 1 / 2 . As discussed before, the t 1 / 2 of a zero order reaction is given as In general, for a reaction of orde..
