Question

Consider the following reaction, the rate expression of which is given below A + B C rate = k [A]1/2 [B]1/2 The reaction is initiated by taking 1M concentration A and B each. If the rate constant (k) is 4.6 × 10–2 s–1, then the time taken for A to become 0.1 M is_____sec. (nearest integer)
