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.
That depends on what the reaction is. Do you have more info related to this problem?
Answer:
The opposite of an endothermic process is an exothermic process, one that releases or "gives out" energy, usually in the form of heat and sometimes as electrical energy.

Answer: Option (1) is the correct answer.
Explanation:
The molecular structure is as follows.
This compound contains carbon (C) atoms, hydrogen (H) atoms, oxygen (O) atoms.
Or, the chemical formula of this compound is 
.
Thus, we can conclude that there are five carbon atoms, eight hydrogen atoms and two oxygen atoms.
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
