9.8 ## Chapter 9### 9.8 If the concentrations of reactants and products are known for a given chemical reaction at equilibrium, the equilibrium constant can be evaluated. Write the equilibrium constant expression for the following equation and substitute the given molarities to calculate a numerical value for Keq.**Equation:**\[2H_1(g) \leftrightarrow H_2(g) + I_2(g)\]**Condition:**In a 1.0 L container, there are:- 2.3 moles HI- 0.45 mole \[ H_2 \]- 0.24 mole \[ I_2 \]### 9.9 Le Chatelier’s principle (Sec. 9.9) considers the effects of outside forces on systems at chemical equilibrium. According to this principle, a stress applied to the system can favor the chemical reaction that will reduce the stress — either the forward reaction, in which case more product is formed, or the reverse reaction, in which case more reactants form. Some of the stresses that can cause this readjustment of the chemical equilibrium are concentration changes, temperature changes, and pressure changes.a. Indicate whether each change in conditions below would shift the chemical equilibrium of the following chemical reaction to the left or to the right:**Chemical Reaction:**\[CH_4(g) + 2O_2(g) \leftrightarrow CO_2(g) + 2H_2O(g) + \text{heat}\]**Table:**| Change in conditions | Equilibrium Change | Explanation ||--------------------------------------------|--------------------|--------------------------------------------------|| increasing the concentration of \[ O_2 \] | | || increasing the temperature of the reaction | | || introduction of an | | |*Note: The detailed explanations and outcomes for each condition's effect on equilibrium would be in the table.***Graph/Diagram Explanation:**There is no specific graph or diagram depicted to explain in detail.
