WebThere are four main factors that can affect the reaction rate of a chemical reaction: Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period. Webincreases the rate of a reaction does not alter the products of the reaction is not chemically changed or used up at the end of the reaction Only a very small mass of catalyst is needed...

WebAn example. In the manufacture of ammonia by the Haber Process, the rate of reaction between the hydrogen and the nitrogen is increased by the use of very high pressures. In fact, the main reason for using high pressures is to improve the percentage of ammonia in the equilibrium mixture, but there is a useful effect on rate of reaction as well. WebThe external Thiele modulus is a function of the mass transfer coefficient and is a function of the flow rate and particle size. Noting that rmax is proportional to the surface area of the particle, we obtain. (16.25) A condition for negligible external mass transfer effects, that is, ηe > 0.95, is given by. (16.28)
