At 700 K, CCl4 decomposes to carbon and chlorine. The Kp for the decomposition is 0.76. Find the starting pressure of CCl4 at this temperature that will produce a total pressure of 1.2 atm at equilibrium. P=?

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

Therefore, the law of mass action is:

Pressure of carbon at equilibrium is not considered since it is solid. In such a way, based on the law of mass action, at equilibrium we have:

And in the law of mass action:

Now, from the total pressure, we have that:

And we combine:

Thus, solving for we have to roots:

Clearly, the solution must be 0.323 atm, in such a way, the initial pressure turns out:

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
