A certain first-order reaction (A→products) has a rate constant of 8.10×10−3 s−1 at 45 ∘C. How many minutes does it take for the
stira [4]

Answer:

The answer is 5.7 minutes

Explanation:

A first-order reaction follow the law of Ln [A] = -k.t + Ln [A]_{0}. Where <em>[A]</em> is the concentration of the reactant at any <em>t</em> time of the reaction, [A]_{0} is the concentration of the reactant at the beginning of the reaction and <em>k</em> is the rate constant.

Dropping the concentration of the reactant to 6.25% means the concentration of A at the end of the reaction has to be [A]=\frac{6.25}{100}.[A]_{0}. And the rate constant (<em>k</em>) is 8.10×10−3 s−1

Replacing the equation of the law:

Ln \frac{6.25}{100}.[A]_{0} = -8.10x10^{-3}s^{-1}.t + Ln[A]_{0}

Clearing the equation:

Ln [A]_{0}.\frac{6.25}{100} - Ln [A]_{0} = -8.10x10^{-3}s^{-1}.t

<em>Considering the property of logarithms: </em>Ln A - Ln B = Ln \frac{A}{B}

Using the property:

Ln \frac{[A]_{0}}{[A]_{0}}.\frac{6.25}{100} = -8.10x10^{-3}s^{-1}.t

Clearing <em>t </em>and solving:

t = \frac{Ln \frac{6.25}{100} }{-8.10x10^{-3}s^{-1} } = 342.3s

The answer is in the unit of seconds, but every minute contains 60 seconds, converting the units:

342.3x\frac{1min}{60s} = 5.7min

What would the products of a double-replacement reaction between KBr and CaO be? (Remember: In double-replacement reactions, the
11111nata11111 [884]

ANSWER

\begin{gathered} \text{ 2KBr }+\text{ CaO }\rightarrow\text{ K}_2O\text{ }+\text{ CaBr}_2 \\ Option\text{ B} \end{gathered}

EXPLANATION

Given that;

The two reactants are KBr and CaO

Double replacement reaction is a type of chemical reaction that occur when two reactants exchange cations and anions to yield new products.

\text{ 2KBr + CaO  }\rightarrow\text{ K}_2O\text{ + CaBr}_2

Therefore, the resulting products of the given data are K2O + CaBr2

The correct answer is option B
