For a particular reaction, Δ H ∘ = 73.5 kJ ΔH∘=73.5 kJ and Δ S ∘ = 193.7 J/K. ΔS∘=193.7 J/K. Assuming these values change very little with temperature, at what temperature does the reaction change from nonspontaneous to spontaneous?

How can the number of core electrons be determined from the periodic table

What is the temperature in kelvin of a gas if it is allowed to expand from 1.50 l to 4.50 l? the initial temperature is 10.0°c and pressure is constant throughout the change. which equation should you use? t2= v2/v1 t1 what is the final temperature? ⇒ 849 k these are the answers.
