The rate of a reaction increases four-fold when the concentration of reactant is increased 16 times. If the rate of reaction is 4×10⁻⁶ mol L⁻¹ s⁻¹ when the concentration of the reactant is 4×10⁻⁴ mol L⁻¹. The rate constant of the reaction will be:
A. 2×10⁻⁴ mol¹/² L⁻¹/² s⁻¹
B. 1×10⁻² s⁻¹
C. 2×10⁻⁴ mol⁻¹/² L¹/² s⁻¹
D. 25 mol⁻¹ L min⁻¹
