Express the equilibrium constant for the combustion of ethanol in the balanced chemical equation. c2h5oh(g)+3o2(g)⇌2co2(g)+3h2o(g) express the equilibrium constant for the combustion of ethanol in the balanced chemical equation. a) k=[c2h5oh][o2][co2][h2o] b) k=[co2]2[c2h5oh][o2]3 c) k=[co2]2[h2o]3[c2h5oh][o2]3 d) k=[co2][h2o][c2h5oh][o2]

The correct answer is C where K=[CO2]^2[H2O]^3/[C2H5OH][O2]^3

Explanation:

Equilibrium constant (K) is expressed as the product of all the products divided by the product of all reactants. the coefficient in front of each reactants or products are used as their exponents. Solids and liquids are considered to be 1 hence they are not shown, but in this case everything is in gaseous form thus they are all expressed in the equilibrium formula formula.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
