<reasoning>

Match chemical kinetics and thermodynamics

Using the Oxidation Numbers and Redox Rules knowledge points, we analyze statements 16–18:

• Statement 16: When forward and reverse rates are equal, the system is at chemical equilibrium (c).
• Statement 17: A reaction releasing free energy is a spontaneous reaction (a).
• Statement 18: The measure of disorder is entropy (b).

Match redox chemistry definitions

We analyze statements 19–21:

• Statement 19: A substance that accepts electrons is reduced, acting as an oxidizing agent (c).
• Statement 20: A substance that donates electrons is oxidized, acting as a reducing agent (d).
• Statement 21: The integer related to electrons under an atom's control is the oxidation number (a).

Match electrochemistry definitions

We analyze statement 22:

• Statement 22: Using electrical energy to drive a non-spontaneous chemical change is electrolysis (b).

Match organic reaction types

We analyze statements 23–25:

• Statement 23: Adding hydrogen to a double bond to form an alkane is a hydrogenation reaction (d).
• Statement 24: Adding water to an alkene is a hydration reaction (c).
• Statement 25: The loss of hydrogen is a dehydrogenation reaction (e).

Identify periodic table arrangement

We analyze statement 26:

• Statement 26: The modern periodic table is arranged by increasing atomic number (c).
