Calculate the percent yield of iron if 950 g of Fe304 underwent the reaction shown in the chemical equali below and 533 g of Fe was isolated from the reaction mixture. Fe304 (s) + 2 C(s)---> 2 CO2 (9) + 3 Fe(s)

Which is not true regarding reaction rates? (2 points) catalysts are not used up in the reaction. catalysts speed up reactions by lowering the activation energy. reaction rates decrease as the concentration of reactants decrease. during reactions, concentrations of all reactants decrease at the same rate.
