In the first 15.0 s of the reaction, 1.7×10−2 mol of O2 is produced in a reaction vessel with a volume of 0.440 L . What is the
Step2247 [10]

Answer:

Rate=2.57x10^{-3}\frac{M}{s}

Explanation:

Hello,

In this case, for the reaction:

2N_2O(g) \rightarrow  2N_2(g)+O_2(g)

We can easily compute the average rate by firstly computing the final concentration of oxygen:

[O_2]=\frac{0.017mol}{0.440L}=0.0386M

Then, we compute it by using the given interval of time: from 0 seconds to 15.0 seconds and concentration: from 0 M to 0.0386M as oxygen is being formed:

Rate=\frac{0.0386M-0M}{15.0s-0s}\\ \\Rate=2.57x10^{-3}\frac{M}{s}

Regards.

What enthalpy change accompanies the reaction 2Al(s) + 3H₂O(l) → Al₂O₃(s) + 3H₂(g)?
Lorico [155]

Answer:

818.6 KJ/mol

Explanation:

2Al(s) + 3H2O(l) → Al2O3(s) + 3H2(g)

∆H=∆Hp-∆Hr

∆H=(1(∆HAl2O3)+3(∆HH2))-(2(∆HAl)+3(∆HH2O))

∆H=((-1676.0 KJ/mol)+3(0 KJ/mol))-(2(0 KJ/mol)+3(-285.8 KJ/mol))

∆H=-818.6 KJ/mol
