Question:
The irreversible, homogeneous, gas-phase reaction A + B -> R, is taking place isothermally in an ideal, constant-volume batch reactor. The temperature is 200 °C and the initial total pressure is 3 atm. The initial composition is 40 mol % A, 40 mol% B, and 20 mol% N2. The ideal gas laws are valid. The reaction obeys the rate equation:
-rA = kCACB
At 100 °C, k = 0.0188 l/mol-min. The activation energy of the reaction is 85 kJ/mol.
1. What is the value of the rate constant at 200 °C? k = 6.19 L/mol-min
2. What is the fractional conversion of A after 30 min? x = 0.86
3. What is the total pressure in the reactor after 30 min? P = 1.98 atm
