PLEASE ANSWER FAST hydrocarbon C10H16 (limonene) dissociates into two molecules of 2-dimethylbutadiene (isoprene C5H8). When this reaction was run at 400k the initial concentration of C10H16 (0.120 mol/L) decreased to 0.030 mol/L at t = 180s. and to 0.001875 mol/L at t=540s. The initial reaction rate for this dissososition was a) 9.125 x 10 -5 mol^2 L^-2 s^-1 b) 6.825x...
