The liquid-phase reaction A+B-->R+S takes place in a 100 L continuously stirred tank reactor operating isothermally and at steady state. The rate of formation of R is given by k*CA*CB and the rate constant, k, is 7 L mol-1 min-1. Two feed streams, one containing 4.60 mol/L of A and the other containing 1.20 mol/L of B are introduced in equal volumes into the reactor. What is the initial concentration of the limiting reactant after the two streams immediately mix as they enter the CSTR?

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
