The following (unbalanced) reaction is one of the steps to producing acid rain [as h2so4(aq)] from sulfur-containing coal. in a study of this reaction, a flask contains an equilibrium concentration of the three substances so2(g), o2(g) and so3(g) held at a constant temperature.

so2 (g) + o2 (g) < > so3 (g)

the concentrations at equilibrium are found to be: [so2] = 3.61 x 10-3m [o2] = 6.11 x 10-4 m [so3] = 1.01 x 10-2 m

(a) write the equilibrium constant expression, kc for this specific reaction.
(b) calculate the value of kc for this temperature.
(c) would you classify this as a product-favored reaction?

a) kc= [SO3 ]/([SO2 ][O2 ])

b) kc= 2.27*10⁶ M⁻¹

v) the reaction is product-favored

Explanation:

for the reaction, the equilibrium constant is

SO2 (g) + O2 (g) <> SO3 (g)

he equilibrum constant is

kc= [SO3 ]/([SO2 ]*[O2 ])

replacing values

kc= [SO3 ]/([SO2 ]*[O2 ]) = 1.01*10⁻² M/(3.61*10⁻³M*6.11 x 10⁻⁴ M) = 2.27*10⁶ M⁻¹

since kc>>1 the reaction is product-favored

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
