A certain reaction X + Y → Z is described as being first order in [X] and third order overall. Which of the following statements is or are true? (i)The rate law for the reaction is: Rate = k[X][Y]2. (ii)If the concentration of X is increased by a factor of 1.5, the rate will increase by a factor of 2.25. (iii)If the concentration of Y is increased by a factor of 1.5, the rate will increase by a factor of 2.25.

Ethanol (c2h5oh) is produced from the fermentation of sucrose in the presence of enzymes. c12h22o11(aq) + h2o(g) 4 c2h5oh(l) + 4 co2(g) determine the theoretical yield and the percent yields of ethanol if 680. g sucrose undergoes fermentation and 326.5 g ethanol is obtained. theoretical _ g _ percent %
