From he calculations, we can see that the total pressure at equilibrium is 21 atm.
<h3>What is equilibrium constant?</h3>
The term equilibrium constant commonly describes the constant that that shows the extent of conversion of reactants to products.
We have to find the pressure of each gas as follows;
For H2
P = nRT/V = 4.553 /2 × 0.082 × 1000/8.89 L = 21 atm
Using the ICE table;
C(s) + 2H2(g) ⇌ CH4(g)
I 21 atm 0
C -x +x
E 21 - x x
0.263= x/(21 - x )^2
0.263(21 - x )^2 = x
38 - 11x - 0.263x^2 = x
0.263x^2 + 12x - 38 = 0
x=2.97 atm
At equilibrium, we have;
(21 - 2.97) + 2.97 = 21 atm

Answer:
The process that converts a solid mcompound into a gas is sublimation.
E.g- dry ice, solid iodine and ammonium salts
when the above solid are heated, only particles which are found on the surface of the solid gain enough energy and break all forces of attraction and form a gas.
Explanation:
False
explanation
All of the elements with atomic numbers 1 to 92 can be found in nature, have stable or very long half-life isotopes, and are created as common products of the decay of uranium and thorium.
