It would be A. Solid-gas temperature increases ( think of a block of ice, you have to increase temperature to make it melt, then the water would evaporate into a gas)

Using the following bond energies:
uranmaximum [27]

Answer:

The answer is "Option b".

Explanation:

Given equation and value:

\Rightarrow C_2H_2 \ (g)+ \frac{5}{2}O_2 \ (g) \longrightarrow 2CO_2\ (g)+H_2O\ (g)

\left\begin{array}{ccc}C \equiv  C&839\\C-H &413\\O=O &495\\ C=O &799\\ O-H &467 \end{array}\right \\\\

calculating equation value:

\Rightarrow 839 + 2(413) +\frac{5}{2} (495) \longrightarrow 2(2)799+2 \times 467 +E

\Rightarrow 839 + 826 +1237.5 = 3196+934 +E\\\\\Rightarrow 2902.5 =4130 +E\\\\\Rightarrow 2902 = 4130 +E\\\\\Rightarrow 2902 - 4130 +E\\\\\Rightarrow E = -1228 \ KJ \\\\

The isomerization of methylisonitrile to acetonitrile is first order in CH3NC. CH3NC(g) → CH3CN(g) The half life of the reaction
sasho [114]

<u>Answer:</u> The rate constant for the given reaction is 4.33\times 10^{-6}s^{-1}

<u>Explanation:</u>

For the given chemical equation:

CH_3NC(g)\rightarrow CH_3CN(g)

We are given that the above equation is undergoing first order kinetics.

The equation used to calculate rate constant from given half life for first order kinetics:

t_{1/2}=\frac{0.693}{k}

The rate constant is independent of  the initial concentration for first order kinetics.

We are given:

t_{1/2} = half life of the reaction = 1.60\times 10^5s

Putting values in above equation, we get:

k=\frac{0.693}{1.60\times 10^5s}=4.33\times 10^{-6}s^{-1}

Hence, the rate constant for the given reaction is 4.33\times 10^{-6}s^{-1}

Which sample of ethanol has particles with the highest average kinetic energy?
ale4655 [162]
The second one.
Remember, temperature is the AVERAGE kinetic energy. So, looking for highest average kinetic energy means looking for highest temperature, which is 55.
Note: the amount of the substance does not determine the average kinetic energy.
