What is the following diagram representing? Energy of products Activation energy Heat of Energy of reaction reactants Progress of reaction exothermic reaction, heat is released endothermic reaction, heat is absorbed exothermic reaction, heat is absorbed endothermic reaction, heat is released Energy

. Consider the exothermic reaction CO(g)+2H2(g)CH3OH(l)Predict three changes that could be made to the system that would decrease the yield of product over that produced by a system in which no change was made.

Sketch energy diagrams to represent each of the following. Label the diagrams completely and tell how they are similar to each other and how they are different. a. Exothermic exergonic reaction with activation energy b. Exothermic exergonic reaction without activation energy

xplain why aluminum cans make good storage containers for soft drinks. Styrofoam cups can be used to keep coffee hot and cola cold. How can this be?

. Before two molecules can react, chemists envision that the molecules must first collide with one another. Is collision among molecules the only consideration for the molecules to react with one another?

. Hydrogen gas and chlorine gas in the presence of light react explosively to form hydrogen chloride H2(g)+Cl2(g)2HCl(g)The reaction is strongly exothermic. Would an increase in temperature for the system lend to favor or disfavor the production of hydrogen chloride?
