please help me on my homework~ reaction engineering~~please....?

The endothermic liquid-phase elementary reaction

A+B===> 2C

Proceeds, substantially, to completion in a single steam-jacketed, continuous-stirred reactor (Table P8-5). From the following data. Calculate the steady-state reactor temperature:

Reactor volume :125 gal

Steam jacket area: 10 ft^2

Jacket steam: 150 psig (365.9 F saturation temperature)

Overall heat-transfer coefficient of jacket, U: 150 Btu/lb.mol of A (independent of temperature

Table P8-5

Component

Feed (lb mol/hr) :10.0(A) 10.0(B) 0(C)

Feed temperature (F) :80(A) 80(B) -(C)

Specific heat (Btu/lb.mol.F)*:51.0(A) 44.0(B) 47.5(C)

Molecular weight :128(A) 94(B) 222(C)

Density (lb/ft^3) :63.0(A) 67.2(B) 65.0(C)

* Independent of temperature

Update:

what is NRG?

    You need to look at the algorithm in this chapter for solving CSTR's.

    It will have you make 2 curves. One curve is a material balance, and the other is an NRG balance. Where the 2 curves intersect will be the steady state operation of the reactor.
