The molar specific heat of many materials at low temperatures is found to obey the Debye law C_v = A[T/theta]^3 where A is a constant equal to 1.94 x 10^3 Jmol^-1K^-1 and with the Debye temperature theta taking different values for different materials. For diamond, it is 1860 K.
(a) Evaluate c_v at 20 K and 100 K.
(b) How much heat is required to heat one mole of diamond between 20 K and 100 K?
(c) What is the average molar specific heat in this range?
question 1a the radiation protection act 2003 makes provisions for the protection of people against the risks from
The feed is a saturated liquid at 330 kPa. The recovery of toluene in the distillate should be greater than 99%, and the recovery of ethylbenzene in the bottoms should be greater than 99%.
An elementary second order adiabatic reaction A+ B CD ? + is taking place in a CSTR. The feed to the reactor is equimolar A and B at concentrations of 2.4 mol/liter. The entering temperature is 300 K.
Chlorine is to be removed from a vent stream by scrubbing with a 5% w/w aqueous solution of sodium hydroxide. The vent stream is essentially nitrogen, with a maximum concentration of 5.5% w/w chlorine.
