Calculate the delta s rxn at 25 degrees celsius for the reaction 2nh3(g)-> > n2h4(g) + h2(g). do you know where i can find these values of the s for these compounds?

In order to find your answer you need to be measuring entropy, so you will be using the following formula:
delta S= S of (N2H4) + S of ( H2) - [2( S of NH3)]
Hope this is very useful for you
