#### Factors Affecting Chemical Equilibrium Chemical equilibrium is a dynamic state in a chemical reaction where the rate of the forward reaction is equal to the rate of the reverse reaction. Several factors can affect the equilibrium position of a chemical reaction, including changes in concentration, temperature, pressure, and the addition of catalysts. #### Matching Factors and Direction of Shift Let's match the factors mentioned in the question with their corresponding direction of shift in the chemical equilibrium: A) **Addition of water** - The addition of water to the system will shift the equilibrium towards the products of the reaction. This is because water is a reactant in the forward reaction and its addition will drive the reaction forward to consume the excess water. Therefore, the equilibrium will shift to the right, towards the products. [[1]] B) **Addition of methane** - The addition of methane to the system will shift the equilibrium towards the reactants of the reaction. This is because methane is a reactant in the reverse reaction and its addition will drive the reaction backward to consume the excess methane. Therefore, the equilibrium will shift to the left, towards the reactants. [[2]] C) **Decrease in pressure** - A decrease in pressure does not cause a shift in the equilibrium position of the reaction. The equilibrium position is determined by the relative concentrations of the reactants and products, not the pressure. Therefore, there will be no shift in the equilibrium position. [[3]] D) **Increase in pressure** - An increase in pressure will shift the equilibrium towards the side with fewer moles of gas. In this reaction, there are fewer moles of gas on the product side (CO and H2) compared to the reactant side (CH4 and H2O). Therefore, an increase in pressure will shift the equilibrium towards the products, to reduce the pressure by consuming the reactants. The equilibrium will shift to the right, towards the products. [[4]] #### Summary To summarize, the matching factors and their corresponding direction of shift in the chemical equilibrium are: A) Addition of water - Shifts towards the products. B) Addition of methane - Shifts towards the reactants. C) Decrease in pressure - No shift in equilibrium position. D) Increase in pressure - Shifts towards the products.
