Hydrogen is prepared commercially by the reaction of methane and water vapor at elevated temperatures. ch₄ + h₂ ⇌ 3h₂ + what is the equilibrium constant for the reaction if a mixture at equilibrium contains gases with the following concentrations: ch₄, 0.126 m; h₂o, 0.242 m; co, 0.126 m; h₂ 1.15 m, at a temperature of 760 °c?

6.2846

Explanation:

Given that:-

Concentrations at equilibrium :-

The equilibrium reaction is:-

The expression for equilibrium constant is:

Applying the values as:-

The equilibrium constant for the reaction is:- 6.2846

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
