Which of these statements best describes the relationship between temperature and reaction rates? Please explain each answer to why it is or isn't correct.
A) If the enery of the products is less than the energy of reactants then the speed of collision has no effect on the rate of the reaction.
B) The energy of the collision of molecules must be great enough to overcome the bond energy of the products.
C) An increase in temperature increases the energy of the collision and rate of reaction.
D) An increase in temperature causes the molecules to collide with greater energy, increasing the rate of the reaction.
For many compounds, it is possible to draw multiple Lewis dot structures that are simplifications of the structure of the true molecule. The actual structure of the molecule
If 30mL of 6.8M H2SO4 was spilled , what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid.
