Hydrogen gas and iodine vapor react as H2(g)+ I2(g) → 2HI(g). The activation energy of the formation of HI is 1.03x102 kJ whereas the activation energy of the dissociation of HI is 1.77x102 (a). Calculate the enthalpy of reaction for the reaction. (b). Sketch the energy profile for the reaction between hydrogen and iodine. Platinum acts as a catalyst for the reaction above. Sketch the energy profile for the catalyzed reaction in the energy profile. (c). Name the type of catalysis involved and explain qualitatively how the presence of platinum catalyzes the reaction above.
