Question

i) What is the action of chlorine on the following. (a) Fe (b) Excess of NH3

ii) What is rate law?
iii) Why is Fe3+ more stable than Fe2+?​

Answer 1

Answer:

Here is the solution

Explanation:

i. Chlorine when reacted with excess of ammonia gives ammonium chloride and nitrogen.

ii. A rate law shows how the rate of a chemical reaction depends on reactant concentration. For a reaction such as aA → products, the rate law generally has the form rate = k[A]ⁿ, where k is a proportionality constant called the rate constant and n is the order of the reaction with respect to A.

iii. Fe3+ is more stable than Fe2+. ... In Fe3+ ions, there are five 3d half-filled orbitals and is more symmetrical than Fe2+. Whereas in Fe2+ ion there are four 3d half-filled orbitals and one orbital is filled.

Answer 2

Answer:

(i) excess of NH3

(ii) Rate law is the expression in which reaction rate of given in terms of molar concentration of reactants with each term raised to some power, which may or may not be same as the stoichmetric coefficient of the reaction.
