rate law

It is an equation that relates the true rate of reaction to the concentrations of the reactants raised to some power. Rate law expression serves three purposes. (i) If the composition of the reaction mixture and the rate constant are known, then the rate..

Experimentally, it is found that the rate of a reaction is proportional to the concentrations of the reactants raised to some power, provided that other factors, which also affect the rate of the reaction are kept constant. For e.g., for the hypothetical reaction, the rateh..

This involves the determination of the values of the exponents 'm' and 'n' as given in the expression (equation 8). The units of the rate constant k depend on the order of the reactio..

Gas Laws - Charles' Law - Jacques Alexander Cesar Charles, a French chemist, discovered in 1787, that at a constant pressure, with rise in temperature, carbon dioxide, hydrogen, oxygen and nitrogen, all expanded at constant rates..

Newton's second law of motion states that rate of change of momentum is directly proportional to applied force and takes place in the same direction as the applied forc..

From kinetic theory, Since the rate of diffusion of a gas is determined by the molecular speed,..

Gases have the tendency to spontaneously intermix and form a homogenous mixture without the help of external agency. This is due to the presence of large amount of empty space between the gas molecules that makes their movement rapid into each other. The gases move from a region of higher concentr..

Newton's Second Law of Motion - Earlier we have mentioned that application of force can change the velocity of the moving object. Let us suppose that a body of mass 'm' is moving with a velocity 'u'. When a force F is applied on the body for 't' seconds, the velocity changes from the init..

Earlier we have mentioned that application of force can change the velocity of the moving object. Let us suppose that a body of mass 'm' is moving with a velocity 'u'. When a force F is applied on the body for 't' seconds, the velocity changes from the initial velocity 'u' to the final velocity 'v'..
