a) when Kc = concentration of products / concentration of reactants
So according to the reaction equation:
Br2(g) + Cl2(g) → 2BrCl(g)
∴ Kc =[BrCl] ^2 / [Br2][Cl2]
b) when q = [BrCl]^2 / [Br2][Cl2]
and we have [BrCl] = 3 m
[Br2] = 1 m
[Cl2] = 1 m
So by substitution:
q= 3^2 / 1*1 = 9
- and we can see that q > Kc
the reaction is not at equilibrium that means there are more products and the reaction shifts to the left to increase the reactants and decrease the products to achieve equilibrium.
C) by using ICE table:
Br2(g) + Cl2(g) → 2BrCl (g)
initial 1 1 3
change -X -X +X
Equ (1-X) (1-X) (3+X)
when Kc = [Brcl]^2/[Cl2][Br2]
by substitution:
7 = (3+X)^2 / (1+X) (1+X) by solving this equation for X
∴X = 0.215
so at equilibrium:
∴ [Br2] = [Cl2] = 1-0.215 = 0.785 m
[BrCl] = 3+0.215 = 3.215 m
Answer:
D
. A substance with a pH of 8
Explanation:
pH stands for <em>"Potential for Hydrogen." </em>This is an indicator of a solution's acidity or alkalinity. It is also used to tell <em>which chemicals are great for cleaning. </em>
pH 7 and pH 8 are both considered<em> "neutral pH,"</em> thus, solutions with these pH are often used as<em> dishwashing detergents </em>because they do not destroy the surfaces of objects. However, pH 8 is said to be<u> more alkaline in nature</u>. This allows it to destroy the residues, such as <em>fats and oils</em>, in pots and pans. It is the<em> pH of baking soda.</em>
