Suppose it takes 27 min for 3.0 g of sugar to completely react with another reagent we added to the flask. What would the reaction rate be?

Must be negative.substance increases

What are the statements?

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
