Beginning at time t=0, cigarette smoke containing 4% carbon monoxide is introduced into the room at the rate of 0.1 cubic foot perminute, and the well-circulated mixture is allowed to leave the room at the same rate. If carbon monoxide levels in the air reach 0.012%, it is harmful to the human body. Find the time at which this unhealthy level is reached.

What is the conversion of A at the exit of the reactor?حد يدبرلنا طريقة حل فرع C A research group discovers a new version of happyase, which they call happyase*, that catalyzes the chemical reaction HAPPY ⇌ SAD. The researchers begin to characterize the enzyme. (a) In the first experiment, with [Et] at 4 nM, they find that the Vmax is 1.6 μM s−1. Based on this experiment, what is the kcat for happyase*? (Include appropriate units.) (b) In another experiment, with [Et] at 1 nM and [HAPPY] at 30 μM, the researchers find that V0 = 300 nM s−1. What is the measured Km of happyase* for its substrate HAPPY? (Include appropriate units.) (c) Further research shows that the purified happyase used in the first two experiments was actually contaminated with a reversible inhibitor called ANGER. When ANGER is carefully removed from the happyase preparation and the two experiments repeated, the measured Vmax in (a) is increased to 4.8 μM s−1, and the measured Km in (b) is now 15 μM.
