Answer:

Gibbs equation helps us to predict the spontaneity of reaction on the basis of enthalpy and entropy values directly. When the reaction is exothermic, enthalpy of the system is negative making Gibbs free energy negative. Hence, we can say that all exothermic reactions are spontaneous.

A mechanism for the decomposition of ozone is (2 O3 â†’ 3 O2). O3 â‡Œ O2 + OO + O3 â†’ O2 + O2What is the molecularity for the f

Gnesinka [82]

Answer:

The correct answer is option c.

Explanation:

Molecularity is defined as number of atoms , ions or molecules that must collide with one another so as to result in a chemical reaction.It is simply the sum of molecules of different reactants as represented in balanced chemical equation.

Reaction taking place in one step are said to be elementary reaction.

Reaction taking place in more than one step are said to be complex reaction.

A mechanism for the decomposition of ozone is given as:

1) $O_3 \rightarrow O_2 + O$

Molecularity for the first elementary reaction is 1. This because single ozone molecule is present.

2) $O + O3\rightarrow O_2 + O_2$

Molecularity for the second elementary reaction is 2. This because single ozone molecule reacts with 1 oxygen atom.
