Why don’t all thermodynamically favored reactions occur rapidly?
a. because thermodynamics and reaction rates are unrelated properties.
b. the reactants still need to break bonds and overcome the activation energy in order to form products.
c. the equilibrium of the reaction favors the reactants and not the products.
d. because thermodynamically favored reactions have positive free energy.

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
