In using the reaction quotient Q to analyze reaction progress, for the condition where Q<
Norma-Jean [14]

Answer:

The correct answer is reaction will achieve equilibrium by forming more products and will move in left to right direction.

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_{eq}

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

  • If Q > K_{eq}  , then the equilibrium will shift in left direction or in backward direction.the reaction will move back to the formation of reactants from the product
  • If Q < K_{eq}  , then the equilibrium will shift in right direction or in forward direction.The reaction will form more products

What are the molecular an empirical chemical formula of a compound made up of these molecules? (Look at Photo)The line stand for
Naya [18.7K]

The molecular formula gives us the total number of atoms of the compound. To do this we are going to count each of the atoms.

We have:

C = 4

H = 8

O = 2

So, the molecular formula will be C4H8O2

The empirical formula is the simplest way to represent a molecule, we simplify taking the denominators of the molecule to its simplest form, as they are all multiplies of two we can divide everything by this number and thus we obtain the empirical formula.

So, the empirical formula will be C2H4O
