Consider the reaction 2 NO (g) + H2 (g) = N20 (g) + H2O (g) with AH° = + 36 kJ. In which direction, left or right, will the equilibrium shift if the following changes are made? 1. NO is added 2. the system is cooled 3. Hz is removed 4. pressure is increased 5. N20 is added 6. H2 is removed

LE CHATELIER'S PRINCIPLE STRESS SHIFT WHY? increase concentration of away from substance extra concentration a substance needs to be used up need to produce more of substance to make up for decrease concentration towards substance of a substance what was removed towards fewer moles of increase pressure of system for gas: pressure increase = volume decrease gas decrease pressure of system towards more moles of for gas: pressure decrease = volume increase gas increase temperature of away from heat/ energy system extra heat/ energy must be used up exothermic reaction is favored more heat/ energy needs to be decrease temperature of towards heat energy system exothermic reaction is favored produced to make up for the loss The rates of both the forward and reverse reactions are increased by the same amount. add a catalyst NO SHIFT Table is lifted from https://socratic.org/questions/what-is-le-chatelier-S-principle-in- chemistry. From the definition of Le Chatelier's principle, assess the following instances: (Note: Use the provided table as a guide.)
