Hydrogen gas and oxygen gas react violently to form water.

ol type='a'>

  • Which is lower in energy: a mixture of hydrogen gases, or water? Explain.
  • i>Sketch an energy-level diagram (like Fig. 10.5) for this reaction and explain it.

    Interpretation Introduction

    (a)

    Interpretation:

    From a mixture of hydrogen gas or water, which is lower in the energy of should be determined.

    Concept Introduction:

    For an exothermic reaction, energy is released thus, the energy of reactant is more than that of product.

    The minimum amount of energy required to start a chemical reaction is known as activation energy.

    Explanation

    It is given that mixing hydrogen gas with oxygen gas results in a violent, an exothermic reaction. It is known that the energy is lost from the system during this process...

    The sketch of the energy level diagram should be determined.

    Concept Introduction:

    For an exothermic reaction, energy is released thus, the energy of reactant is more than that of product.

    The minimum amount of energy required to start a chemical reaction is known as activation energy.
