feasibility

• what is a feasible reaction?

  one that will occur and proceed on its own, under standard conditions, with no need for intervention or changes being made to external conditions.
• what is 1 factor that can influence the feasibility of a chemical reaction?

  the enthalpy change of a reaction.
• what can we use overall enthalpy change to see?


  if a reaction is exothermic or endothermic.
• what overall enthalpy change would an endothermic reaction have?

  a positive one.
• what overall enthalpy change would an exothermic reaction have?

  a negative one.
• are all exothermic or endothermic reactions feasible or not feasible?

  no, some will be feasible and can proceed without any interference but other reactions won't be feasible and can't proceed without interference to external factors.
• what can we deduce from the fact that some endothermic reactions are feasible and others aren't?

  the value of enthalpy change is important but it isn't the only factor that determines feasibility.
