<h3>What is the concentration of the original hydrochloric acid acid?</h3>
The concentration of the original or stock hydrochloric acid is calculated as follows:
- Molarity = Percentage concentration * Density * 1000/Molar mass * 100
Molarity of stock HCl = 36 * 1.18* 1000 /36.5 * 100
Molarity of stock HCl = 11.6 mol/dm
i. Using the dilution formula: M₁V₁ = M₂V₂
M₂ = M₁V₁ /V₂
M₂ = 11.6 * 10/1000
M₂ = 0.116 M
The new concentration = 0.116 M
ii. Using M₁V₁ = M₂V₂
M₂ = M₁V₁ /V₂
M₂ = 0.116 * 5/20
M₂ = 0.029 M
The new concentration = 0.029 M
In conclusion, the new concentrations are found using the dilution formula.

Answer:
The correct option is;
A) x = 2, y = 1
Explanation:
Here we have
![k[0.05]^x \cdot [0.05]^y = 0.062 \ M/sec](https://tex.z-dn.net/?f=k%5B0.05%5D%5Ex%20%5Ccdot%20%5B0.05%5D%5Ey%20%3D%200.062%20%5C%20M%2Fsec)
....................(1)
![k[0.05]^x \cdot [0.10]^y = 0.123 \ M/sec](https://tex.z-dn.net/?f=k%5B0.05%5D%5Ex%20%5Ccdot%20%5B0.10%5D%5Ey%20%3D%200.123%20%5C%20M%2Fsec)
....................(2)
![k[0.100]^x \cdot [0.100]^y = 0.491 \ M/sec](https://tex.z-dn.net/?f=k%5B0.100%5D%5Ex%20%5Ccdot%20%5B0.100%5D%5Ey%20%3D%200.491%20%5C%20M%2Fsec)
..............(3)
From experiment (1), (2) it is observed that [A] is held constant and [B] is doubled of which the rate is also observed to be doubled, therefore, when you double a reactant which result in the rate being doubled, the order of the reaction with respect to the reactant is order 1, therefore, y = 1.
Similarly between reaction (2) and (3) when the concentration of the reactant B is doubled and A is held constant the rate of the reaction is multiplied by a factor of 4, therefore, the reaction with respect to that reactant is order 2, therefore, x = 2.
Therefore, the correct option is x = 2, y = 1.
