When doing an experiment with Boyle's Law, would a different in the type of gas affect the results? For example, if CO2 was used instead of air.
The reaction can be represented as {\rm 2 NI_3 (s)\rightarrow N_2 (g) + 3 I_2 (g)},~{{\Delta H}}_{\rm rxn} = -290.0~{\rm kJ} Find the change in enthaply when 16.0g of \rm NI_3 decomposes.
Assume all the step reactions except the rate determining step are fast reactions and at equilibrium, which step reaction, do you think, is the rate determining step? (a)Cl2 -> 2Cl (b)H2 +Cl -> H2Cl (c) H2Cl + Cl2 -> 2HCl +Cl (d) none of the above..
