For a single-phase multiple reaction system, consider the following equilibria: C02(g) + 3H2(g) ↔ CH30H(g) + H20(g) reation1

C02(g) + H2(g) ↔ C0(g) + H20(g) reation2

The initial mixture comprises 2 moles of CO2, 5 moles of H2 and 1 mole of CO.

(a) Develop expressions for the mole fractions of the reacting species as a function of the extent of reaction for the above two reactions.

(b) You can assume that all gases in both reactions are ideal gases and the pressure of reactor is kept at 2 bar and is at equilibrium. If the extents of reactions for the above reactions are 0.6 (reaction 1) and 0.8 (reaction 2), calculate the equilibrium constants for both reactions.

(c) For this system, suggest a possible approach to increase the yield of CH3OH.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

he would use the colour black

the answer would be b i believe
