This reaction is endothermic. If you were a chemist trying to maximize the amount of C2H4I2 produced, which of the following might you try? Assume that the reaction mixture reaches equilibrium. (a) decreasing the reaction volume (b) removing I2 from the reaction mixture (c) raising the reaction temperature (d) adding C2H4 to the reaction mixture C2H41g2 + I21g2 C2H4I21g2
