It is determined experimentally that the reaction e + f → x + y is second order with respect to e and first order with respect to f. which of the following statements is correct? view available hint(s) it is determined experimentally that the reaction e + f → x + y is second order with respect to e and first order with respect to f. which of the following statements is correct? halving the concentration of e will decrease the reaction rate by half. doubling the concentration of e will have no effect on the rate. doubling the concentration of e will increase the reaction rate by a factor of four. doubling the concentration of f will cause the reaction rate to increase by a factor of four.
