DENIUS [597]3 years ago

The overall order of a reaction is directly related to the reaction mechanism of the reaction. The reaction mechanism is defined by the reaction rate equation. In this case, we are given by the equation, Rate=k. The order of this reaction is zero since the rate is not dependent on the concentration of reactants or products.

Answer: The order of the reaction for the given rate law is zero.

Explanation:

Order of the reaction is defined as the sum of the exponents or powers to which the molar concentration in the rate law equation are raised to express the observed rate of the reaction. For a given general equation:

aA\rightarrow cC+dD

Rate law is given as: Rate=k[A]^a

Order of the reaction will be = a

For the given rate law: Rate=k[A]^0

In the rate law, anything raised to power 0 is 1.

Order of the give rate law = 0

And, hence, the order of the reaction will be zero.

A 7.74 L balloon is filled with water at 3.88 atm. If the balloon is squeezed into a 0.23 L beaker and does NOT burst, what is t
Vladimir [108]

Answer:

131 atm

Explanation:

To find the new pressure, you need to use Boyle's Law:

P₁V₁ = P₂V₂

In this equation, "P₁" and "V₁" represent the initial pressure and volume. "P₂" and "V₂" represent the final pressure and volume. You can find the new pressure (P₂) by plugging the given values into equation and simplifying.

P₁ = 3.88 atm                       P₂ = ? atm

V₁ = 7.74 L                           V₂ = 0.23 L

P₁V₁ = P₂V₂                                                      <----- Boyle's Law

(3.88 atm)(7.74 L) = P₂(0.23 L)                       <----- Insert values

30.0312 = P₂(0.23 L)                                      <----- Simplify left side

131 = P₂                                                          <----- Divide both sides by 0.23

Calculate the no. of each atoms presents in 10 grams of calcium carbonate.
raketka [301]

Molar Mass of Calcium carbonate:-

\\ \sf\longmapsto CaCO_3

\\ \sf\longmapsto 40u+12u+3(16u)

\\ \sf\longmapsto 52u+48u

\\ \sf\longmapsto 100u

\\ \sf\longmapsto 100g/mol

  • Given Mass=10g

\boxed{\sf No\:of\;moles=\dfrac{Given\:Mass}{Molar\:Mass}}

\\ \sf\longmapsto No\:of\;moles=\dfrac{10}{100}

\\ \sf\longmapsto No\:of\:moles=0.1mol

Now

\boxed{\sf No\:of\:molecules=No\;of\:moles\times Avagadro\: No}

\\ \sf\longmapsto 0.1\times 6.023\times 10^{23}

\\ \sf\longmapsto 6.023\times 10^{22}molecules
