Two different reactions begin with equal concentrations of their respective reactants, A and C. Both reactions proceed, but reaction 1 has a faster initial rate than reaction 2 . Both reactions are allowed to react for an extended period of time. Reaction 1: AB faster initial rate Reaction 2:CD slower initial rate Identify the conclusion that cannot be made based on the information given. The concentrations of C and D do not change at equilibrium. Reaction 2 has a smaller concentration of products at equilibrium. Reaction 1 and reaction 2 can both reach equilibrium. Reaction 1 reaches equilibrium more quickly than reaction 2
