pseudo zero order

Pseudo First Order Reaction - For a reaction A + B C + D. The rate law for the reaction is expressed as rate = k [A] m [B] n If the concentration of B is kept large, then [B] essentially does not change over time and if the rate of reaction is determined as rate = k [A] then thi..

Example 4: Ammonia (NH 3 ) gas decomposes over platinum catalyst to nitrogen gas (N 2 ) and hydrogen gas (H 2 ). The chemical reaction is as follows: fig 6.4(a) - Concentration versus time profile for a zero order reacti..

Relationships for Zero order, First order and Second order Reactions..

Rates of most chemical reactions increases with temperature because the rate constant 'k' increases with temperature. The temperature dependence of the rate constant is given by the Arrhenius equatio..

A matrix of order m x n whose elements are all 0 is called a null matrix (or zero matrix) of order m x n. It is usually denoted by O or more clearly [O] m , n..

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 obtained..

Graphical Method of Order Determination - 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 calculati..

Recognize the incorrect statement(s). I. A distribution having only one mode is called unimodal. II. The class with largest frequency is called model class. III. The price of bread packet for 7 consecutive years is $2.00, $2.20, $2.70, $3.00, $3.10, $3.60, $3.90. The mode of the given data is ..

Absolute Entropies and Third Law of Thermodynamics - The third law of thermodynamics deals with the entropies of the perfect crystalline substances at absolute zero of temperature. According to third law of thermodynamics: At absolute zero the entropy of a perfectly crystalline ..
