The reaction is run at two temperatures where temperature 1 is lower than temperature 2.  Which relationship is correct for either rate constant (k1 or k2) or activation energy (Ea,1 and Ea,2)?

In addition to dispersion forces, what intermolecular forces are present in a solution between methanol (CH3OH) and bromine (Br2)?

What are the Brønsted-Lowry bases in this reaction? NH3(aq) + H2O(l) ⇌ NH4+(aq) + OH–(aq)

The pH of a 0.050 M aqueous solution of ammonium chloride (NH4Cl) falls within what range?

Which process would be predicted to have ΔS < 0?

The activation energy for the reaction of               2NO2(g) 

On the energy diagram, point A denotes the _____, a _____ energy transition state where bonds may break and/or form.    

Which substance would have the greatest standard molar entropy?

How much time (in s) is needed to deposit 0.0125 g of chromium from a solution of Cr(NO3)3 with a current of 1.50 A?  The molar mass of chromium is 52.00 g∙mol–1.

This is a reason for A and B to have a statistically insignificant correlation (association), even though there actually is a causal relationship between them: “A” is a necessary but not sufficient condition for B.
