A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 25.0cm wide and 30.0cm high. The maximum safe pressure inside the vessel has been measured to be 7.10MPa.For a certain reaction the vessel may contain up to 1.68kg of sulfur tetrafluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Round your answer to 3 significant digits.
1) Suppose that the initial number of bacteria in a culture is 200, and that there are 700 bacteria present after 2 days. How long would it take for the number of bacteria to reach 4000?
2) A bowl of soup originally at 140 F is sitting in a 70 F room. After 10 minutes, the soup has cooled to 120 F. How long will it take for the soup to cool to 90 F?
4. Temperature effect on the decomposition of drug Y was evaluated at two temperatures; 40 and 60°C. If the first-
