The following graph shows the progression of a reaction between molecular hydrogen (H2) and molecular (I2) to produce hydrogen iodide (HI). Referencing the graph, answer the next seven questions.   See the description for details “This image depicts a graph showing the progression of a chemical reaction between molecular hydrogen (H2) and molecular iodine (I2) to form hydrogen iodide (HI). The red line represents the concentration of H2(reactant). The black line represents the concentration of I2 (reactant). The red dashed line represents the concentration of HI (product).The vertical line marked “”A”” is used as a reference for further questions regarding the concentration progression over time.”
