  • At a constant temperature, the yield of product at equilibrium is not changed by adding a catalyst (1); however, many processes are so slow that they never reach equilibrium in the absence of a catalyst, so in that sense an added catalyst increases the yield by enabling the reaction mixture to reach equilibrium (1). •Answer: The product formed for the following reaction is acetaldehyde. The reaction of methanenitrle with HCl in the presence of anhydrous stannous chloride yields aldimine complex as an intermediate, which on hydrolysis results into the formation of acetaldehyde.
