Question

The pH of a 1.0 L buffer solution containing 0.2 mol of acetic acid (CH ₃ COOH) and 0.3 mol of sodium acetate (CH3COON a) is 5. 0. The Ka of acetic acid is P x 10 ⁻⁵ , where the numerical value of P (rounded off to one decimal place) is __

Explanation

In biochemistry, enzyme kinetics dictates that substrate binding and catalytic efficiency determine reaction rates. Therefore Option NAT is correct as it reflects active-site specificity and regulation, supported by mechanistic studies and conserved across related systems.
