Consider the following equilibrium: co2(g) + c(graphite) 2co(g); δh = 172.5 kj the equilibrium constant for this reaction will
a. increase if the temperature is decreased.
b. decrease with increasing temperature.
c. increase with increasing temperature.
d. increase at some pressures and decrease at other pressures.
e. not change if the temperature is increased.

Option (B) is the correct answer.

Explanation:

As the given reaction is as follows.

Equilibrium constant for this reaction will be as follows.

According to Le Chatelier's principle, when we increase the temperature then the equilibrium will shift towards the right hand side.

As a result, concentration of carbon dioxide will decrease whereas concentration of carbon monoxide will increase.

Thus, we can conclude that in the given reaction equilibrium constant for this reaction will decrease with increasing temperature.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
