Which of the following statements about the combustion of glucose with oxygen to form water and carbon dioxide (C6H12O6 + 6 O2 →
worty [1.4K]

Answer:

The correct statement is:

E - The entropy of the products is greater than the entropy of the reactants.

Explanation:

C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O

As glucose is a large molecule and then it is transformed into many molecules of water and carbon dioxide, the entropy of the system increases. If the number of molecules increases, the disorder increases.

Initial state: 7 molecules (1 glucose + 6 oxygen)

Final state: 12 molecules (6 carbon dioxide + 6 water)

Part A In a particular experiment at 300 ∘C, [NO2] drops from 0.0138 to 0.00886 M in 374 s . The rate of disappearance of NO2 fo
sweet-ann [11.9K]

Answer:

The rate of disappearance of NO_2 for this period is-1.32\times 10^{-5} M/s

Explanation:

Initial concentration of NO_2 = x = 0.0138 M

Final concentration of NO_2 = y = 0.00886 M

Time elapsed during change in concentration = Δt = 374 s

Change in concentration ,\Delta [NO_2]= y - x = 0.00886 - 0.0138 M = -0.00494 M

The rate of disappearance of NO_2 for this period is:

\frac{\Delta [NO_2]}{\Delta t}=\frac{-0.00494 M}{374 s}=-1.32\times 10^{-5} M/s
