What information is not given by an overall equation for a chemical reaction?

a) the number of atoms participating in the reaction

b) the reaction mechanism

c) the relative numbers of molecules used

d) the probable order of the reaction

Option (b) is the correct answer.

Explanation:

A chemical equation is an equation in which participating atoms that are written on left hand side are known as reactants and atoms that are written on right hand side are known as products.

For example,

Also, a reaction equation will help us determine the order of a reaction when it shows elementary step.

But a reaction equation does not show the mechanism of the reaction.

Hence, we can conclude that information that is not given by an overall equation for a chemical reaction is the reaction mechanism.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.
