Which of the following describes the entropy change of a gas reaction? O A. If there is an increase in the number of gas molecules, then AS< 0. OB. If there is an increase in the number of gas molecules, then AS = 0. O C. If there is an increase in the number of gas molecules, then AS> 0. O D. The change in entropy cannot be predicted in a gas reaction.​

Consider this equilibrium: n29) + o2(g) + 2no(c).nitrogen gas and oxygen gas react when placed in a closed container. as the reaction proceeds towards equilibrium, what happens to the rate of thereverse reaction?

Which element has the lowest electronegativity? calcium(ca) gallium(ga) selenium(se) bromine(br)

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.
