Question

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 22.0cm wide and 26.4 cm high. The maximum safe pressure inside the vessel has been measured to be . For a certain reaction the vessel may contain up to 0.833 kg of boron trifluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Be sure your answer has the correct number of significant digits.

Explanation / Answer

KgMoles of boron triflouride = 0.833/67.82 = 0.0123kg moles

volume = 10035.5 cubic cm = 10035.5 litre

so, max. temperaure = P*V/(n*R*T) = 696.75 K = 423.75 C
