Cherries Posted May 3, 2018 Report Share Posted May 3, 2018 The diagrams below represent equilibrium mixtures for the reaction Y + X2 ->/<- XY + X at 350 K and 550 K respectively. Deduce and explain whether the reaction is exothermic or endothermic. (350 K VS. 550 K) Thank you in advance! Reply Link to post Share on other sites More sharing options...
kw0573 Posted May 3, 2018 Report Share Posted May 3, 2018 For exothermic reactions, an increase in temperature will shift equilibrium back to reactants. At 350K, there were 1Y and 1X2 but at 550K there were 3Y and 3X2. Because there were more reactants, so it was an exothermic reactions. 1 Reply Link to post Share on other sites More sharing options...
