Question

I need help! In an equilibrium reaction with a Keq of 1 × 108 A. products are favored. B. the reaction is nonspontaneous. C. the reaction is endothermic. D. reactants are favored.

Answer 1

Answer: The correct answer is Option A.

Step-by-step explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants. It is represented as
`K_(eq)`

For the general reaction:

`A+B\rightarrow C+D`

Expression for equilibrium constant is given as:

`K_(eq)=([C][D])/([A][B])`

Conditions for
`K_(eq)` are:

`K_(eq)>1`, then products are favored

`K_(eq)=1`, then forward reaction is equal to backward reaction

`K_(eq)<1`, then reactants are favored

As,
`K_(eq)=1* 10^8` and is very much greater than 1, so products will be favored.

Hence, the correct answer is Option A.

Answer 2

When K is > than 1 products are favored. When q is < less than 1 reactants are favored. 1 x 108 = 108 which is > 1 so products are favored.
