The equation below was correctly written on the board, representing the CSTR mole balance, ' 0 ' * ' * ' * * ) 1 ( ) 1 ( n n A n A n A A A AO T T X X kC X r X C AO + - = - = ε τ (1) Since k = A exp(-E/RT) according to the Arrhenius equation, we rewrote the above

Unformatted text preview: CSTR mole balance (1); however, this was done incorrectly, because it was missing the 1 '-n AO C term in the denominator: ' * 1 ' ' * * ' ) 1 ( ) 1 ( ) / exp( n A n n A A n X C X X RT E T T AO-+ =- -(2) Please make a note of the corrected equation (2) above....
