In a batch reactor, reactant A undergoes a certain reaction to form product B. The concentrations of A and B with respect time are shown in the plot below. Concentration over time for the reaction 4,5 35 Concentration (mol/L) 3 0.5 0 0 1 1.5 2 2.5 3 3.5 4 4.5 Time (min) -Concentration of A 5 5.5 6 -Concentration of B 6.5 7 Reactant A has a stoichiometric coefficient of -1 (i.e., VA = -1). Determine the stoichiometric coefficient for product B (round to the nearest integer). Assume the system has constant volume and temperature. (6 pts) A+bB
