Write the expression for the equilibrium constant kc of the following reaction. (concentration equilibrium expressions take the general form: kc = [c]c / [a]a . [b]b. subscripts and superscripts that include letters must be enclosed in braces {}.) hc3h7co2 + nh3 equilibrium reaction arrow c3h7co2− + hnh3+

Explanation:

The equilibrium constant is calculated as the product of the products raised to the power of their stoichiometric coefficients divided by the product of the reactants raised to the power of their stoichiometric coefficients. This expression includes only gases and aqueous species.

Given the equation:

HC₃H₇CO₂ + NH₃ ⇄ C₃H₇CO₂⁻ + HNH₃⁺

This is an acid-base reaction that takes place in water, so Kc is:

Refrigerators work by causing the refrigerant circulating inside them to change from a liquid into a gas     Explanation:   Its :

called evaporation, cools the surrounding area and produces the desired effect.
