The question is missing parts. The complete question is as follows.
Consider the two gaseous equilibria involving SO2 and the corresponding equilibrium constants at 298K:
⇔ 
; 
⇔ 
The values of the equilibrium constants are related by:
a) = 
b) 
c) 
d) 
Answer: c)
Explanation: <u>Equilibrium</u> <u>constant</u> is a value in which the rate of the reaction going towards the right is the same rate as the reaction going towards the left. It is represented by letter K and is calculated as:
![K=\frac{[products]^{n}}{[reagents]^{m}}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5Bproducts%5D%5E%7Bn%7D%7D%7B%5Breagents%5D%5E%7Bm%7D%7D)
The concentration of each product divided by the concentration of each reagent. The indices, m and n, represent the coefficient of each product and each reagent.
The equilibrium constants of each reaction are:
⇔
![K_{1}=\frac{[SO_{3}]}{[SO_{2}][O_{2}]^{1/2}}](https://tex.z-dn.net/?f=K_%7B1%7D%3D%5Cfrac%7B%5BSO_%7B3%7D%5D%7D%7B%5BSO_%7B2%7D%5D%5BO_%7B2%7D%5D%5E%7B1%2F2%7D%7D)
⇔ 
![K_{2}=\frac{[SO_{2}]^{2}[O_{2}]}{[SO_{3}]^{2}}](https://tex.z-dn.net/?f=K_%7B2%7D%3D%5Cfrac%7B%5BSO_%7B2%7D%5D%5E%7B2%7D%5BO_%7B2%7D%5D%7D%7B%5BSO_%7B3%7D%5D%5E%7B2%7D%7D)
Now, analysing each constant, it is easy to see that is the inverse of .
If you doubled the first reaction, it will have the same coefficients of the second reaction. Since coefficients are "transformed" in power for the constant, the relationship is:
Answer:
Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth ’s density is 5.51 grams per cubic centimetre. Density can also be expressed as kilograms per cubic metre (in MKS or SI units). For example, the density of air is 1.2 kilograms per cubic metre.

Answer:
Tom is correct. The rate of reaction of Crystal violet and NaOH is first order with respect to NaOH, hence, a higher concentration of NaOH corresponds to a higher rate of reaction; a faster reaction.
This means the speed of cleaning depends on the concentration of the lye used.
Explanation:
The reaction between Crystal violet and NaOH, represented as
CV⁺ + OH⁻ → CVOH
It is a reaction that is know to turn the violet colour of the crystal violet colourless.
The rate of the reaction is also known to be second order; first order with respect to Crystal violet and first order with respect to NaOH.
This means that the rate of reaction is directly proportional to the concentration of NaOH provided all other parameters such as the rate constant and the concentration of Crystal violet are constant.
Hence, the reaction becomes faster with an increased concentration of NaOH.
So, Tom is right, concentrated lye solution would remove the stain faster.
Bob is wrong.
Hope this Helps!!!
Given that the metal is reactive, like magnesium is, the ions of the metal displace the hydrogen ions released by the acid and the metal ions combine with the acid's anions, forming a salt. The displaced hydrogen ions are released in the form of hydrogen gas. The reaction equation is as follows:
Acid + metal → salt + hydrogen gas
Thalia would need to consider how big the sphere is , the mass of the sphere, permits required for the sphere, and how much it would cost to make the sphere.
Hope this helps!
