Macmillan Learning Consider a chemical reaction between molecules A, B, and C. The reaction is first order with respect to A, zero order with respect to B, and second order with respect to C. Write the rate law for the chemical reaction. rate = What happens to the reaction rate when the concentration of A is doubled while the concentrations of the other reactants are held constant? The reaction rate doubles. The reaction rate increases by a factor of 4. The reaction rate decreases by one half. The reaction rate remains the same. What happens to the reaction rate when the concentration of B is doubled while the concentrations of the other reactants are held constant? The reaction rate doubles. The reaction rate increases by a factor of 4. The reaction rate decreases by one half. The reaction rate remains the same.

Add the two vectors shown to form a resultant vector R-> , and report your result using polar vector representation. Take x = 1.6 ft and y = 1.4 ft. (Round the final answers to four decimal places.) The sloped vector x and the sloped vector y pass through each other.The sloped vector x is directed in the top-right direction at an angle of 60 degrees with the horizontal. The sloped vector y is directed in the bottom-right direction at an angle of 45 degrees with the horizontal. The polar vector representation for R-> is R-> = 1.1628 Numeric ResponseEdit Unavailable. 1.1628 incorrect.ft @ \deg ⦨. (The direction of the resultant is measured from the right hand horizontal direction.)

4) Solve the following initial value problems. For each case, what is the limit of the solution as \(t \to \infty\)? (a) \(y'' + 3y' + 2y = 0, y(0) = -1, y'(0) = 4\) Answer: \(y(t) =\) \(\lim_{t \to \infty} y(t) =\) (b) \(y'' + 2y' + y = 0, y(0) = 1, y'(0) = -3\) Answer: \(y(t) =\) \(\lim_{t \to \infty} y(t) =\)

3. (a) Assuming that Hooke' law holds up to the point of failure, show that the theoretical cleavage strength of a material may be given by $\sigma_{th} = \left(\frac{4\gamma E}{a}\right)^{1/2}$ where $\gamma$, E and a are surface energy, Young's modulus, and spacing between cleavage planes of the material, respectively. (b) By considering a material with an elliptic crack of half-length c and crack tip radius of curvature $\rho$ show that for a sharp crack, the maximum stress at the crack tip is given by $\sigma_{max} = 2\sigma_a\sqrt{(c/\rho)}$

DAA instruction works as below: 1. If auxiliary carry bit is 1 or the content of the 4 low order bits of accumulator is higher than 9, DAA adds 06 to the 4 low order bits. 2. If carry bit is 1 or the content of the 4 high order bits of accumulator is higher than 9, DAA adds 06 to the 4 high order bits. Assuming DAA command does not exist, write a code in 8085 assembly language to implement exactly the same function. Use stack to read flag register and initialize the SP with 11FFH.

The input for the code will include the rate constants k of the reactions and the initial concentrations [C] of the reactants. The output of the code will include the concentrations of both the reactants and products as a function of time.

Good quality soybeans are harvested, cleaned, hulled, and pressure-cooked. The cooked soybeans are ground by a number of grinders that transform the beans into milky slurry. The dilute-phase pneumatic transport system carrying 148 kg/hr of a grinded soybeans powder (density 479.8 kg/m$^3$, mean particle size 41.12 µm) from hulled soy beans to the grinder with internal diameter of 13.02 mm across a horizontal distance of 11 meters and a vertical distance of 3.42 meters using ambient air ($\rho$= 1.2 kg/m$^3$, $\mu$ = 18.4 x 10$^{-6}$ Pa.s). The slurry is placed in a centrifuge that extracts any insoluble bits of bean as shown in Fig Q2. The separated soy liquid called jun is blended with vitamins, flavorings, and sugar and then sterilized and homogenized. The hot milk is cooled and packaged in such a way that it is never exposed to air. Assume that the frictional factor, $f_g$ = 0.005 Determine: (i) the saltation velocity, (5 marks) (ii) the horizontal voidage, (5 marks) (iii) the mass flux, (5 marks) (iv) the gas friction, (5 marks) (v) the horizontal pressure.
