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 $4.33\times 10^{-6}s^{-1}$

Find the number of moles in 6120 ions of NaCl . Round your answer to two decimal places. Input your answer as 1.03E23, which is

FrozenT [24]

Answer:

Explanation:

NaCl = Na⁺ + Cl⁻

6120 ions of NaCl will contain 3060 ions of Na⁺ and 3060 ions of Cl⁻ , forming 3060 molecules of NaCl .

6.02 x 10²³ molecules of NaCl = 1 mole

3060 molecules of NaCl = 3060 x 10⁻²³ / 6.02 moles

= 508.30 x 10⁻²³ moles

= 5.08 x 10⁻²¹ moles

Answer : 5.08E-21 moles .
