What is the half-life (in minutes) of this reaction when the initial C4H6 concentration is 2.40102 Butadiene (C4H6) reacts with itself to form a dimer M ? with the formula (C8H12). The reaction is second order in C4H6. If the rate constant at a particular temperature is 4.0102M1s1. Part B How many minutes does it take for the concentration of C4H6 to drop from 1.20102M to 3.00103M? Express your answer using two significant figures
