Could I get help with 2c to check if I got the correct answer.

**Problem 2: Consider the following three weak monoprotic acids** - **Acetic acid (CH₃COOH)**: \( K_a = 1.8 \times 10^{-5} \) - **Benzoic acid (C₆H₅COOH)**: \( K_a = 6.5 \times 10^{-5} \) - **Nitrous acid (HNO₂)**: \( K_a = 4.5 \times 10^{-4} \) --- **a) The strongest acid is (circle the correct answer):** - Acetic acid (CH₃COOH) - Benzoic acid (C₆H₅COOH) - Nitrous acid (HNO₂) **b) The strongest conjugate base is (circle the correct answer):** - Acetate ion (CH₃COO⁻) - Benzoate ion (C₆H₅COO⁻) - Nitrite ion (NO₂⁻) **c) The value for \( K_b \) for C₆H₅COO⁻ (benzoate ion)** (Note: Make sure to calculate its value based on the given \( K_a \) for benzoic acid.)
