A certain reaction of the general form A + A → Products, follows the second order rate law with respect to reactant A. If the rate constant, k, is 0.042 M⁻¹ min⁻¹, and the initial concentration of reactant A is 4.83 M, what is the concentration of reactant A in molarity (M) after 4.3 minutes of reaction? Do not include unit. Keep 2 decimal places in your answer?
a) 2.25
b) 2.50
c) 2.75
d) 3.00
