Answer to Question #213038 in General Chemistry for Alaa Aboukhadra

Question

For a reaction system at chemical equilibrium that includes some, but not all, gaseous species

the reaction is always shifted to side with largest total moles of only gas species

the reaction is always shifted to the left if the pressure increases

the reaction is always shifted to side with fewest total moles of all species

the reaction is always shifted to side to reduce gaseous matter interactions

the reaction is always shifted due to molar mass of species due to a kinetic molecular theory postulate

the reaction is always shifted to side with smallest total moles of all species

the reaction is always shifted to side with smallest total moles of only gas species

 

the reaction is always shifted due to a kinetic molecular theory postulate to minimize repulsions

Answer 1

If the concentration of one (or more) of the reactants or products is increased the equilibrium will shift to decrease the concentration. Or if the temperature is decreased the equilibrium will shift to increase the temperature by favouring the exothermic reaction.
