Here are some problems and their answers. I would appreciate ifsomeone could please explain step by step how to get these answers?I need to understand this concept.
The following questions refer to the equilibria: 2NaHCO3(s) ⇌ Na2CO3(s) + H2O(g) + CO2(g) K(110°C)=0.68
1)If CO2(g) is added to the equilibrium mixture the partialpressure of H2O(g) will: answer: Decrease (how and why??)
2) If the volume of the container is decreased, the amount ingrams of sodium carbonate (Na2CO3(s)) will: Answer: decrease (Ithought volume only affects gases??)
3)The ΔH of the reaction was measured and determined to be -25kJ/mole of sodium bicarbonate (NaHCO3). If the reaction were run at150°C, a possible value for K could be: answer: 0.54

This next question is not involved with the above.
4) What is the pH of the solution after 30 mL of 0.12 M HCl ismixed with 60 mL of 0.12M NaOH? Answer: . 12.60
