Any factor that causes molecules to collide more frequently speeds up the reaction rate. This is achieved by an increase of the reactants concentration, surface area, raised temp. , raised pressure of gaseous reactant, or an addition of catalysts to the reactant
Hydrochloric Acid would best be described as an Arrhenius and BrØnsted-Lowrey acid.
<h3>
Is Hydrochloric Acid considered a
Brønsted-Lowry acid?</h3>
Hydrochloric Acid HCl(g) is the proton donor and therefore a Brønsted-Lowry acid.
<h3>
Is Hydrochloric Acid considered an Arrhenius
acid?</h3>
According to Arrhenius theory, hydrochloric acid is an acid which gives hydrogen ions in water but according to Bronsted-Lowry theory, hydrochloric acid is an acid because it donates a proton to the water molecule.
<h3>Is
Hydrochloric Acid considered a Lewis acid?</h3>
Hydrochloric acid (HCl) cannot be classified as a Lewis acid since it cannot accept an electron pair.
Thus, hydrochloric Acid would best be described as an Arrhenius and BrØnsted-Lowrey acid.

The molarity of the solution is calculated by dividing the number of moles of the solute, in moles, by the total volume of the solution, in liters.
The molar mass of calcium hydroxide, Ca(OH)2 is calculated below.
m = molar mass Ca + 2(molar mass O) + 2(molar mass H)
Substituting,
m = 40 g/mol + 2(16 g/mol) + 2(1 g/mol)
m = 74 g/mol
To get the number of moles Ca(OH)2 in 75.8 grams,
n = (75.8 grams)(1 / 74 g/mol) = 1.024 moles
The molarity, M, is therefore,
M = (1.024 moles Ca(OH)2) / (1.2 L)
M = 0.854 M
<em>Answer: 0.854 M</em>
When there is an increase in pressure, the equilibrium will shift towards the side of the reaction with fewer moles of gas. When there is a decrease in pressure, the equilibrium will shift towards the side of the reaction with more moles of gas.
