Is fermentation endo or exothermic
WebThe increased temperature means that the reaction released energy. Endothermic reactions get cold. Exothermic reactions get hot. The reaction would be probably be exothermic since it involves precipitation of AgBr from the solution. (Edit: and also because the temperature of the reaction mixture is increasing) Here the energetics merely don't ... Web14. Is this reaction endothermic or exothermic?

WebA brief summary of the manufacture of ethanol. Ethanol is manufactured by reacting ethene with steam. The reaction is reversible, and the formation of the ethanol is exothermic. Only 5% of the ethene is converted into ethanol at each pass through the reactor. By removing the ethanol from the equilibrium mixture and recycling the ethene, it is ... WebA chemical reaction in which heat is released is called exothermic reaction. The sign of the enthalpy change is negative. A chemical reaction in which heat is absorbed is called endothermic reaction. The sign of the enthalpy change is positive. Chapter 6, Problem 19Q is solved.
