Referring to Table 20.1, calculate the mole fraction of CO2 and its concentration in parts per million by volume.
CHEM 102: General Chemistry II Spencer Kociba Drexel University Lecture 12 (02/06/17) ● Spontaneity ○ The greater difference in energy between the reactants and the products, the more likely the reaction is to proceed ○ higher a = slower reaction ● Catalysts ○ Affect the rate of a reaction (however overall reaction remains the same) ○ Must have the same concentration at the beginning and the end to be a catalyst ○ Doesn’t change overall energy of the reaction, just the activation energy ○ ■ blue=reaction without catalyst ■ red=same reaction with a catalyst ○
