Answer is: C₄H₈.
C₄H₈ is hydrocarbon, organic compound<span> consisting only of carbon and hydrogen.
CaH</span>₂ (calcium hydride) is alkaline earth hydride, inorganic compound.
H₂O₂(hydrogen peroxide) is pale blue, clear, inorganic <span>liquid.
P</span>₂O₅ (phosphorus pentoxide) is <span>white, crystalline solid inorganic compound.</span>
Answer and Explanation:
The reaction is in the gas phase, so the equilibrium constant is expressed in terms of the partial pressures (P) of the products and reactants, as follows:
We have the following data:
P(SO₃) = 2.6 atm
P(O₂) = 0.43 atm
We need Kp for this reaction. We can assume that in Appendix 4 we found that Kp = 7 x 10²⁴.
Then, we introduce the data in the equilibrium constant expression to calculate the partial pressure f SO₂ (PSO₂), as follows:
Therefore, the partial pressure of SO₂ is 1.5 x 10⁻¹² atm (for the given Kp).
