Route 1:RME = 82.92%MI= 1.34 Route 2RME = 22.84%MI = 18.15 Route 3RME = 57.34%MI = 1.89 Compare the value of Reaction Mass Efficiency (RME) and Mass Intensity (MI) generally, and choose which metrics is more significant in green measurement. Justify your answer.
The enzyme urease is widely used for determining urea concentration in blood. The Michaelis constant for urease at room temperature is 2.0 mM and k2 = 2.5 × 10^3 s^-1 at pH = 7.5. Based on the kinetic experiment, when 4.76 mM urease was used, the initial rate of the reaction was determined to be 8.1 M/sec. What is the concentration in unit of mM of urea in blood? Please keep your answer to two decimal place. Please convert all concentration unit to mM in calculation. The answer is 4.26 (I would need help getting this answer)

In a study of the decomposition of ammonia on a tungsten surface at 1100 °C NH3- →1/2 N2 + 3/2 H, the concentration of NH3 was followed as a function of time. It was found that a graph of [NH3] versus time in seconds gave a straight line with a slope of -4.52x10-6 M s1 and a y-intercept of 5.82×10-3 M. Based on this plot, the reaction is order in NH, and the rate constant for the reaction is Ms!.
