12. The first-order rate constant for the reaction of methyl chloride (CH3Cl) with water to produce methanol (CH3OH) and hydrochloric acid (HCl) is 3.32 × 10−10 s−1 at 25°C. Calculate the rate constant at 52.1°C if the activation energy is 116 kJ/mol. _____ ×10^____ s−1 (Enter your answer in scientific notation.) 14.

24. We had a homework problem in which the Arrhenius equation was applied to the blinking of fireflies. Several other natural phenomena also obey that equation, including the temperature dependent chirping of crickets. A particular species, the snowy tree cricket, has been widely studied. These crickets chirp at a rate of 178 times per minute at 25.0°C, and the activation energy for the chirping process is 53.9 kJ/mol. What is the temperature if the crickets chirp at a rate of...

What is the answer to part
(b), not in scientific notation?
Additional Exercise 13.123 The rate at which crickets chirp depends on the ambient temperature, because crickets are cold blooded insects whose body temperature follows the temperature of their environment. It has been found that the Celsius temperature can be estimated by counting the number of chirps in 8 seconds and then adding 4. In other words, te= (number of chirps in 8 seconds) + 4. Correct (a) Calculate the...

Guests are arriving at a party at a rate of 12 per minute. Each guest will be checked in, served a drink, and accompanied to his/her table by one receptionist, one bartender, and one usher respectively. Both the receptionist and usher can serve 10 guests per minute, whereas the bartender takes 5 minutes to serve one guest. Which resource is the bottleneck and what is the process capacity in guests per minute? (a) Bartender, 0.2 (b) Bartender, 5 ...
