The value of the equilibrium constant K depends on: I. the initial concentrations of the reactants. II. the initial concentratio
Elden [556K]

Answer:

None of these

Explanation:

For a reaction;

aA + bB ------>cC + dD

The equilibrium constant K is given as;

K = [C]^c [D]^d/[A]^a [B]^b

The equilibrium constant neither depends on the concentrations of the reactants nor on that of the products.

Let us recall that at equilibrium, the concentrations of reactants and products remain largely constant. This implies that, concentration of species do not appreciably change at equilibrium because the rates of forward and reverse reactions are equal.

Hence, the equilibrium constant neither depends on the initial/final concentrations of the reactants nor on the initial/final concentrations of the products.

Which describes the correct number and types of atoms in this molecular structure?
Andrews [41]

Answer: Option (1) is the correct answer.

Explanation:

The molecular structure is as follows.

           CH_{3}-CO-CH_{2}-CO-CH_{3}

This compound contains carbon (C) atoms, hydrogen (H) atoms, oxygen (O) atoms.

Or, the chemical formula of this compound is C_{5}H_{8}O_{2}.

Thus, we can conclude that there are five carbon atoms, eight hydrogen atoms and two oxygen atoms.

Dioxane, C4H8O2, has an enthalpy of fusion of 145.8 J g–1 and its melting point temperature is 11.0 °C. How much heat is require
kumpel [21]

Answer:

20703.6J

Explanation:

Quantity of heat (Q) = mass of dioxane × enthalpy of fusion

Mass of dioxane = 142g

Enthalpy of fusion of dioxane = 145.8J/g

Q = 142g × 145.8J/g = 20703.6J
