In which direction will the reaction shift in each of the following situations? By decreasing the temperature (from 900K to 300K), then according to Le-Chatelier’s principle, the equilibrium shifts towards the forward direction where the evolution of heat takes place in order to nullify the effect of a decrease in temperature. It is an endothermic reaction. High pressure is maintained because the moles of the product are less than the moles of reactants. reakcja: 2SO2 + O2 → 2SO3 Po prostu w bezpośrednim sąsiedztwie pyłu Pt przepuszcza się pary SO2, który stopniowo przechodzi w SO3. Determine whether the reaction is endothermic or exothermic, and calculate the total energy change per mole of sulfur dioxide. -Delta H means heat was released, which means the reaction is EXOthermic. The rate of the endothermic reaction will increase. Therefore the equilibrium shifts to left. 1) It doesnt change 2) It may either increase, decrease, or remain the same, depending on the sizes of the temperature and pressure changes 3) It decreases 4) It may either increase, decrease, or remain the same, depending … The reaction being endothermic means that the system absorbs energy; in essence, you can put the term "heat" on the left: 2SO3(g) + Heat ↔ 2SO2(g) + O2(g) Now use LeChatelier's principle: the reaction will proceed in the direction to relieve the stress. Please register to post comments. Predict what will happen if the tem­perature is increased. The rate of the endothermic reaction will decrease.
