Pressure
Explanation:
Pressure is a measure of force per unit area.
Pressure is defined as the force exerted on a body across a unit area. The unit of pressure is N/m² or Pascal.
Pressure = 
The more the force acting on a body the more the pressure felt. A small surface area and a large force increases pressure on a body.
it is right to say that pressure is proportional to force but inversely proportional to area.

The final concentrations of water, isopentyl acetate, isopentyl alcohol, and acetic acid obtained on using equilibrium expression are 3.4M, 3.4M, 0.6M , 4.6M
Using ICE table:-
Acetic acid + Isopentyl alcohol ------> Isopentyl acetate + water
I 8M 4M 0 0
C 8-x 4-x +x +x
E 8-x 4-x +x +x
Equilibrium constant (Keq) = 4.2
On using the equilibrium expression -
Keq = [Product] / [Reactant]
Keq = x^2 / (8-x) (4-x )
4.2 = x^2 / 32 - 8x - 4x + x^2
x = 3.4
Concentration of acetic acid = 8-x = 8-3.4 = 4.6M
Concentration of isopentyl alcohol = 4-x = 4-3.4 = 0.6M
Concentration of isopentyl acetate = x = 3.4M
Concentration of water = x = 3.4M

Answer:
I hope this will help you and Please mark me as Brilliant
Explanation:
Approximately 2 mL of Solution A (on the left) is added to a sample of Solution B (on the right) with a dropping pipet. If a precipitate forms, the resulting precipitate is suspended in the mixture. The mixture is then stirred with a glass stirring rod and the precipitate is allowed to settle for about a minute.
Solution A: 0.5 M sodium hydroxide, colorless
Solution B: 0.2 M nickel(II) nitrate, green
Precipitate: light green
Ni(NO3)2(aq) + 2 NaOH(aq) —> Ni(OH)2(s) + 2 NaNO3(aq)
