Suppose you have a reaction between A and that forms product C: A B C and that A and B are both added at equal concentrations to a reaction vessel. At the end of 120 min you find that the concentration of A is just 30% of what it was originally. You have previously determined that the reaction proceeds as first order in [A] and zero order in [B]. How much of the initial amount of A will remain at the end of 240 min? 9.00 % O 17.6% O 0.000% O 14.2%
