Hello,
I'm just here to ask about question 10 b,c and d about my chemistry hw. May I please get a detailed reply ASAP? Thanks!
Heya, is the new syllabus, I will give it a go!
(10.b) So at point A, Q will increase as the system reaches equilibrium as the equilibrium is shifting to the right, producing more products, and because we know that:
Q = Products/Reactants
Since the concentration of the products is increasing while the concentrations of the reactants is decreasing as the system reaches equilibrium. Thus, you can say that Q is going to increase.
(10.c) So what has happened is that the concentration of lead (Pb) has increased sharply because excess lead has been added to the chamber. From there, the equilibrium is shifting to the right to produce more products to counteract the sharp rise in lead, according to Le Chatelier's Principle. Le Chatelier's Principle states that a system at equilibrium will adjust itself to reduce any change in the system. So in this case, the change is the increase in lead that has been added, thus the system has produced more products (PbNO3) to counteract the change. It then reaches a new equilibrium.
(10.d) that is literally the exact same question as (10.c) so is that a mistake?
Hope this helps!!
