Answer:
e. The inhibitor is a reversible inhibitor.
Explanation:
The reason for which the enzyme has more activity after the chromatography step is that the enzyme was separated from the inhibitor.
The enzyme and the inhibitor could only be separated by size-exclusion chromatography if they had different sizes (which is tipically the case between enzymes and inhibitors) and the inhibitor was a reversible one.
When mixed together, the inhibitor was bonded to the enzyme.
All of these EXCEPT helium in a balloon
Strong base since it is completely soluble
Answer:
T = 552.632 K
Explanation:
Mass of nitrogen = 25.7 g
Volume = 50 L
Pressure = 640 mmHg (640/760 = 0.84 atm)
Temperature = ?
Solution:
Number of moles of nitrogen:
Number of moles = 25.7 g/ 28 g/mol
Number of moles = 0.92 mol
Temperature:
PV = nRT
T = PV/ nR
T = 0.84 atm × 50 L /0.92 mol × 0.0821 L. K⁻¹. mol⁻¹. atm
T = 42 atm. L / 0.076 L. K⁻¹.atm
T = 552.632 K
Answer:
N2O(g) + 3 H2O(l) ---------------> 2 NH3(g) + 2 O2(g)
Explanation:
If we look at the reaction stated in the question, we will notice that the option chosen in the answer is the reverse of that reaction.
One thing is clear, if a reaction is possible, then its reverse reaction is equally possible. The equilibrium position may shift towards the forward or reverse reaction based on the conditions of the reaction.
Hence if the reaction, 2NH3(g) + 2O2(g) → N2O(g) + 3H2O(l) is possible, then the reaction, N2O(g) + 3 H2O(l) ---------------> 2 NH3(g) + 2 O2(g) is also possible.
