Chemical Equilibrium Research Paper

They are two rough question and I would love to have them answered. Document Preview: The data corresponding to the first-order decomposition of a substance A at 250 K are given on page 4 of the exam. However, there are some problems with the information. Specifically, someone tinkered with the experimental apparatus, raising the temperature to 273 K at a certain time, and later raising it again to another, unspecified temperature. Your job is to complete the following: Determine the times where the temperature was raised to 273 K and the unspecified temperature. Determine the specific reaction rate coefficient for the decomposition at 273 K Determine the activation energy for the reaction. Determine the unspecified final temperature that the experimental system was set to. Assuming this is a unimolecular reaction, use the Arrhenius equation information given above (and some surprisingly direct equations in your text) to determine H­, S ­ and G­ for the transition state species at the final, unspecified temperature (that you should know by now).
