<u>Answer:</u> The value of equilibrium constant for the net reaction is 11.37

<u>Explanation:</u>

The given chemical equations follows:

<u>Equation 1:</u>  A+2B\xrightarrow[]{K_1} 2C

<u>Equation 2:</u>  2C\xrightarrow[]{K_2} D

The net equation follows:

D\xrightarrow[]{K} A+2B

As, the net reaction is the result of the addition of first equation and the reverse of second equation. So, the equilibrium constant for the net reaction will be the multiplication of first equilibrium constant and the inverse of second equilibrium constant.

The value of equilibrium constant for net reaction is:

K=K_1\times \frac{1}{K_2}

We are given:

K_1=2.57

K_2=0.226

Putting values in above equation, we get:

K=2.57\times \frac{1}{0.226}=11.37

Hence, the value of equilibrium constant for the net reaction is 11.37

What resources should the scientist use to research water pollution?
Alla [95]
A scientist needs to check several parameters before coming to a conclusion about the amount of water pollution. The scientists needs to check the amount of dissolved oxygen in the water, temperature of the water, the clarity of the water, the PH level of the water and also the amount of bacteria present in the water. There may be other criteria’s, but the mentioned ones are enough to gauge the amount of pollution in the water. Scientists often takes fish and aquatic plants from the water to be tested to check the amount of pollution indirectly affecting these species.

How do purple stem plants use there energy
tatuchka [14]
Purple stem plants can be formed by genetics, they use their energy slightly different from other plants, they use less energy, but that may also be because of bad nutrition, and because they may be hungry for nutrients.
