The statement “The collision theory treats a reaction as a collision between hard spheres” is to be critiqued and compared with the transition state theory. Concept Information: The basic postulate of collision theory is that the rate of a reaction is proportional to the number of effective collisions per second among the reactant molecules. An effective collision is one that actually gives product molecules. Anything that can increase the frequency of effective collisions should, therefore, increase the rate. This theory is also known as a kinetic-molecular theory. The kinetic-molecular theory is used to calculate the frequency of the collision. When molecular collision takes place, the new species is generated as the product in the chemical reaction . Transition state theory determines the reaction rates of elementary reactions. It assumes a type of equilibrium between the intermediate and the reactants.

What is the average mass of the 10 pennies? Report your value with correct significant figures. What is the error (uncertainty) associated with each mass measurement due to the equipment? What is the uncertainty associated with the average value? Note that the uncertainty of the balance will propagate throughout the calculation. What is the standard deviation of the 10 mass measurements? Explain the difference between the propagated uncertainty and the standard deviation. Which number would you use to describe the uncertainty in the measurement? Calculate the total mass of the pennies with associated uncertainty. Calculate the average density of a penny based on these data. Propagate the uncertainty values for both mass and volume in your calculations.
