Choose the strongest acid. acid a, ka = 2.3 x 10-8 acid b, ka = 2.5 x 10-6 acid c, ka = 8.3 x 10-7 acid d, ka = 1.4 x 10-7

The strength of an acid can be predicted from its acid dissociation constant.

For a hypothetical monoprotic acid HA, the dissociation equilibrium is:

HA ↔ H+ + A-

Ka = [H+][A-]/[HA]

Now, higher the Ka value, greater is the dissociation and stronger is the acid strength

Based on the given examples, Ka is the highest for Acid B= 2.5 * 10⁻⁶. Hence Acid B is the strongest acid.

Ans: Acid B

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
