Questions and Answers

What does the term 'kinetics' deal with in chemical reactions?

  • The color change during a reaction
  • The rate of change of displacement (correct)
  • The amount of reactants and products
  • The temperature at which reactions occur

How are chemical reactions classified based on rate?

  • Exothermic, endothermic, and reversible
  • Acidic, basic, and neutral
  • Single displacement, double displacement, and combustion
  • Fast, moderate, and slow (correct)

What does the slope of the reactants curve indicate?

  • Increase in concentration of reactants
  • Decrease in concentration of reactants (correct)
  • Formation of new reactants
  • No change in concentration of reactants
