The diagram shows the potential energy changes for a reaction pathway.
A curve line graph is shown. The y axis of the graph has the title Potential Energy. The x axis of the graph has the title Reaction Pathway. The curve begins at a lower level and ends at a slightly higher level. A vertical line labeled A, starts from the x axis till the beginning of the graph line. A vertical line labeled B starts from the x axis and continues till the peak of the graph. Another vertical line labeled C is shown from the x axis till the point where the curve ends.
Part 1: Does the diagram illustrate an endothermic or an exothermic reaction? Give reasons in support of your answer.
Part 2: Describe how you can determine the total change in enthalpy and activation energy from the diagram and if each is positive or negative.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
