Question

Which set of values tells us if the reaction is at equilibrium?
A
(Ca2+] = 5.8x10-SM
(CO 321 = 5.8x10-5M
B
k= 47M/s
Ksp = 3.34x107

с
Rate of precipitation = 2.1x108 M/
Rate of dissolution = 2.1x108 M/s

Answer 1

Answer:

C

Explanation:

A system is at equilibrium when the rates of opposing reactions are equal.

Answer A does not show the rate of reactions, it only shows concentrations of reactants.

Answer B only shows constants, it does not show rates of reactions.

Answer 2

The set of values that tells us if a chemical reaction is at equilibrium is: C.

Rate of precipitation = 2.1 x 10⁸ M/s.

Rate of dissolution = 2.1 x 10⁸ M/s.

What is a chemical reaction?

A chemical reaction can be defined as a chemical process that involves the continuous transformation (rearrangement) of the ionic, atomic or molecular structure of a chemical element by breaking down and forming chemical bonds, so as to produce a new chemical compound while new bonds are formed.

In Chemistry, a chemical reaction is considered to be at equilibrium when the rates of the forward and backward reactions are equal. Thus, the set of values that tells us if a chemical reaction is at equilibrium is:

• Rate of precipitation = 2.1 x 10⁸ M/s.

• Rate of dissolution = 2.1 x 10⁸ M/s.
