36.9 g. The balanced equation is P4 + 5O2 = P4O10. The moles of P4 present are calculated as 23.9 g x 1 mole/123.88 g = 0.193 moles. The moles of O2 available are 20.8 g x 1 mol/32 g = 0.65 moles O2. According to the balanced equation, the mole ratio of O2 to P4 is 5:1. Therefore, is 0.65 moles O2 equal to 5 times 0.193 moles? The answer is NO, indicating insufficient O2 is available. O2 is thus the limiting reactant. The theoretical moles of P4O10 produced equal 0.65 moles O2 multiplied by 1 mole P4O10 over 5 moles O2, resulting in 0.13 moles P4O10. Consequently, the mass of P4O10 generated equals 0.13 moles times 283.9 g, which is 36.9 g.

castortr0y [3046]

Answer:

B) Hyperbolic curve; substrate saturation

Explanation:

Enzymatic kinetics examines the rates of reactions catalyzed by enzymes. These studies offer insights into the mechanism of the catalytic reaction and enzyme specificity. Determining the reaction rate facilitated by an enzyme is generally straightforward, as purification or isolation of the enzyme is frequently unnecessary. Measurements are taken under optimal conditions for pH, temperature, and the presence of cofactors, utilizing saturating substrate concentrations. Under these circumstances, the observed reaction rate is the maximum velocity (Vmax). The rate can be measured by monitoring either product formation or substrate consumption.

Following the rate of product formation (or substrate consumption) over time yields the so-called reaction progress curve, or merely, reaction kinetics. This reacts as a hyperbolic curve
