10 Find the transition time of 20g naphthalene with the surrounding temperature as 30oC.Let the boiling tube has mass 25 g, diameter 2.5 cm and thickness 0.15cm. How much time does 30g of ice takes to melt at a surrounding temperature of -50C. (We are using a boiling tube having mass= 20g, radius=1.5cm, thickness=0.2cm.) In the above experiment, let the surrounding temperature is changed to 0oC. What will be the change in the transition time for ice? Repeat the experiment for different surrounding temperatures and study the variation of melting point of ice. Calculate the melting point of wax having a mass 30g. Let we are using a boiling tube of mass 25g, having a thickness 0.5 cm and radius 1.5 cm.( Choose surrounding temperature as 40oC)
A research group discovers a new version of happyase, which they call happyase*, that catalyzes the chemical reaction 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 V0300 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 wasactually 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. For the inhibitor ANGER, calculate the values of αand α’.
