Aim: What role does thermochemistry play in explosives? QQ: Calculate G for the following equation: ___ CO 2 (g) + ___ H 2 (g) ___ CH 4 (g) + ___ H 2 O (l) Do Now: What values would you expect for H, S, and G for an explosive material? Why? What needs to be taken into consideration when selecting an explosive? Sensitivity Refers to the ease that a material may be ignited or detonated o Impact how hard can it be hit before exploding? o Friction can it be scratched without exploding? o Heat what temperature can the material withstand before exploding? Decomposition of Nitrogen Triiodide 2NI 3 (s) 3I 2 (g)+ N 2 (g) S = + (increase in entropy) H = - (exothermic) G = - (spontaneous) Stability Refers to the ability of an explosive to be stored without deteriorating o Chemical constitution how much activation energy is needed? A lot “stable” (many composite explosives) A little “liable” ( -NO 2 , -ONO 2 , N 3 ) Brisance

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
