2/17/2021 · 2A + B ? A 2 B, if concentration A is doubled and concentration of B is being half, the rate of reaction will: (a) Increase 4 times (b) Decrease 2 times (c) Increase 2 times (d) Remains unchanged. Question 15. Half life for second order reaction : (a) Is proportional to initial concentration (b) Does not depend upon initial concentration, For the reaction : 2A + B ? A2B the rate = k[A][B]2 with k = 2.0 × 10?6 mol?2 L2 s?1. Calculate the initial rate of the reaction when [A] = 0.1 mol L?1, [B] = 0.2 mol L?1. Calculate the rate of reaction after [A] is reduced to 0.06 mol L?1.
This reaction is first order with respect to reactant A and second order with respect to reactant B.
