Which of the following describes a nonspontaneous reaction? A. The Gibbs free energy is more than the activation energy.
B. The Gibbs free energy is less than the activation energy.
C. The Gibbs free energy for the reaction is positive.
D. The reaction does not need added energy to occur.

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
