UESTION 1 1 poi Consider the following system, initilly at equilibrium in a chamber in which the total pressure can be adjusted by altering the chamber volume C12(g)+2 NO(g) 2 ClNO(g) Which changes should be made to the system in order to maximize the amount of CINO present once equilibrium is restored? O Increasing the amount of NO and decreasing the chamber volume (which increases total pressure), easing the amount of NO and increasing the chamber volume (which decreases total pressure). Increasing the amount of NO and increasing the chamber volume (which decreases total pressure) Decreasing the amount of NO and decreasing the chamber volume which increases total pressure). QUESTION 2 1 points Consider the following equilibrium system for the high-temperature reduction of tinol) oxide (Sn0) by dihydrogen (H2). Which of the following ch in an increased yield of Sn(s) at equilibrium, and why? Sno(s)+ H2(g) Sn(s)+ H20(g) Increasing the pressure of H2(g), because this makes reaction quotient Q smaller than K Increasing the pressure of H2(g), because this makes reaction quotient Q larger than K. Increasing the pressure of H2O(g), because this makes reaction quotient Q smaller than K The yield of Sn will not change, because Sn is a solid that does not appear in the expression for Q. 1 points QUESTION 3Explanation / Answer
1)
Adding reactant will shift the reaction in the direction of product as per Le chatelier Principle
So, Equilibrium moves to product side
Increasing pressure will shift the reaction in a direction which have lesser gaseous molecules as per Le chatelier Principle
Here product has less gaseous molecule
So equilibrium will move to right
So, Equilibrium moves to product side
Answer: option 1 (here we add reactant and increase pressure)
