Which of the following is an incorrect statement?

  1. (a) A mixture of H2 and O2 has lower chemical potential energy than H2O.
  2. (b) Input of energy is required to split an H2 molecule into two H atoms.
  3. (c) Water at 30 °C has a higher thermal energy than the same amount of water at 20 °C.

Interpretation Introduction

Interpretation: Among the given following, the incorrect statement to be identified.

Concept introduction:

Thermal energy: Thermal energy refers to the energy contained within a system and is responsible for its temperature. It is due to the motion of atoms, molecules, or ions at the submicroscopic (particulate) level (thermal energy). All matter ha thermal energy.

Explanation of Solution

Reason for correct option:

a) Generally, chemical potential energy is the energy stored in the chemical bonds of the fuel. While burning the stored chemical energy is released. Thus, in the given mixture of H2andO2 ; the hydrogen gas act as a fuel and the oxygen is used to burn and the process releases vigorous energy. Therefore, the mixture certainly has higher chemical potential. Hence, the given statement is incorrect.

Hence the correct option is option (a).

Reason for incorrect options:

  • Option b) – Input of energy is required to split H2 molecule into two H atoms.

    In order to separate the covalent bonding between two hydrogen atoms, sufficient energy is required to split
