Please answer question #2. Thank you! 22. The activation energy of a certain uncatalyzed biochemical reaction is 50.0 kJ/mol. In the pres-ence of a catalyst at 37°C, the rate constant for the reaction increases by a factor of 2.50 x 10³ ascompared with the uncatalyzed reaction. Assuming the frequency factor, A, is the same for boththe catalyzed and uncatalyzed reactions, calculate the activation energy for the catalyzed reac-tion.23. Experiments during a recent summer on a number of fireflies (small beetles, Lampyridaes photi-nus) showed that the average interval between flashes of individual insects was 16.3 s at 21.0°Cand 13.0 s at 27.8°C.a. What is the apparent activation energy of the reaction that controls the flashing?b. What would be the average interval between flashes of an individual firefly at 30.0°C?24. While looking up recipes in a database, you find several different recipes for baked chicken.These recipes are all very similar (chicken parts, baked in a basting sauce). The only significantdifference is that each recipe specifies a different oven temperature and baking time.Oven Temp (Fahrenheit)350.375.500.300.Baking Time (minutes)90.075.030.0135.Let us simplify this overall process by considering the phenomenological “chemical equation":Raw chicken > Baked chickenAssume that the rate is proportional to the reciprocal of the time. Estimate the activation energyfor the baking of chicken under these conditions by graphing the data above. For how manyminutes should you allow a similar recipe to bake, if you use an oven temperature of 400°F?25. You are investigating a reaction,2 A + B → 2 C. In a particular experi-ment, you follow the concentration of A as afunction of time and produce the graph at right.1.3Ln[A] = -0.0500•Time + 1.250R2 = 0.991.251.2........E 1.15.....

Given: The Experiments during a recent summer on a number or fireflies (small beetles, Lampyridaes photinus). It is showed that the average interval between flashes or individual insects was 16.3 s at 210°C and 13.0 S at 27.8°C. What is the apparent activation energy of the reaction that controls the flashing? What would be the average interval between flashes of an individual firefly at 30.0°C?(a) The reaction apparent activation energy that results in controlling the flashing as below, If the interval between flashes is 16.3s, then the rate is: The value of the calculation is 13.0s:The Activation Energy (Ea) can be calculated using the following formula On substituting the values as, On rearranging the values as,On simplifying the values as,b) The average interval between flashes of an individual firefly at 30.0°Cis calculated by the formula as, On substituting the values as,On simplifying the values as, On rearranging the values as,The Time interval is calculated as, Hence, the interval value is 12 seconds.
