If the equilibrium constant for a reaction is 0.00010, what does this tell us about the position of equilibrium for that reaction?

a. there are more reactants than products at equilibrium.
b. there are more products than reactants at equilibrium.
c. at equilibrium, the concentration of reactants is the same as that of the products.
d. the concentration of the product at equilibrium is 0.00010 m.

A. There are more reactants than products at equilibrium.

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

For a general chemical reaction:

The expression for is written as:

There are 3 conditions:

When ; the reaction is product favored.

When ; the reaction is reactant favored.

When ; the reaction is in equilibrium.

From the above expression, the equilirbium constant is directly dependent on product concentration. Thus, more is the concentration of product, more will be the equilibrium constant.

The values of less than 1 , means the reactant are more than the products.

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

i would say b

explanation:

but i think i would need more information than that
