Answer 1

Question

Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.

(b)

Interpretation Introduction

Interpretation:

Whether the reaction, A+A⇌ B+C, is endothermic or exothermic has to be predicted.

Concept Introduction:

To predict whether a reaction is endothermic or exothermic, find out the change in enthalpy of the reaction which is obtained by subtracting the activation energy of the backward reaction from the forward reaction. If the enthalpy change is positive, it is an endothermic reaction and if it is negative then it is an exothermic reaction

(c)

Interpretation Introduction

Interpretation:

The effect of raising the temperature on the rate constants and equilibrium constant of the reaction has to be predicted.

Concept Introduction:

A reaction is said to be in equilibrium if the rate at which the forward reaction takes place becomes equal to the rate at which the backward reaction takes place. If any of the factors that affect the equilibrium changes, then the reaction shifts in either forward or backward direction so that the equilibrium condition is reestablished.
