how do you determine the maxiumum wavelenth of a phton that could cause a gaseos hydrogen molecule to split into two lone hydrogen atom s

i think its 100

i hope this !

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
