Question

what are zero order and pseudo order reaction

Answer 1

Answer:

Zero-order kinetics is always an artifact of the conditions under which the reaction is carried out. For this reason, reactions that follow zero-order kinetics are often referred to as pseudo-zero-order reactions. Clearly, a zero-order process cannot continue after a reactant has been exhausted.

Answer 2

Answer:

Zero-order reactions are typically found when a material that is required for the reaction to proceed, such as a surface or a catalyst, is saturated by the reactants.

Examples of Zero Order Reactions:

• Photochemical reaction between hydrogen and chlorine:
• Decomposition of N2O on hot platinum surface:
• Decomposition of NH3 in presence of molybdenum or tungsten is a zero-order reaction.

• Iodations of acetone in presence of H+ ions.

A pseudo-first order reaction is a second order reaction whose rate depends on the concentration of two of the reactants, but you supply an excess of one of them in order to consider its concentration constant.

Two examples of first-order reactions:

• The hydrolysis of aspirin and the reaction of t-butyl bromide with water to give t-butanol.
• Another reaction that exhibits apparent first-order kinetics is the hydrolysis of the anticancer drug cisplatin.
