What is the rate constant of a reaction if rate = 1 x 10-2 (mol/L)/s, [A] is 2 M,

boyakko [2]

The rate constant of a reaction : 8.3 x 10⁻⁴

<h3>Further explanation</h3>

Given

rate = 1 x 10⁻² (mol/L)/s, [A] is 2 M, [B] is 3 M, m = 2, and n = 1

Required

the rate constant

Solution

For aA + bB ⇒ C + D

Reaction rate can be formulated:

$\large{\boxed{\boxed{\bold{r~=~k.[A]^a[B]^b}}}$

the rate constant : k =

$\tt k=\dfrac{rate}{[A]^m[B]^n}\\\\k=\dfrac{1.10^{-2}}{2^2\times 3^1}\\\\k=8.3\times 10^{-4}$

Silver nitrate reacts with calcium to make calcium nitrate and silver. The reaction is exothermic and produces 18.7 kJ/mol of en

denis-greek [22]

Answer:

1.63 kilo Joules of energy will be produced when 14.8 g of silver nitrate react.

Explanation:

$AgNO_3+Ca\rightarrow Ag+CaNO_3,\Delta H_{rxn}=-18.7 kJ/mol$

Mass of silver nitrate = 14.8 g

Moles of silver nitrate = $\frac{14.8 g}{170 g/mol}=0.08706 mol$

According to reaction, when 1 mole of silver nitrate reacts with 1 mole of calcium it gives 18.7 kJ of heat.

Then amount of heat released when 0.08706 moles of silver nitrate reacts :

$0.08706\times 18.7 kJ=1.628 kJ\approx 1.63 kJ$

1.63 kilo Joules of energy will be produced when 14.8 g of silver nitrate react.

Describe the orbital diagram of an atom with six electrons. Explain how this orbital diagram demonstrates Hund's rule.

densk [106]

Answer:

See explanation

Explanation:

According to Hund's rule, electrons must occur singly first before pairing takes place.

If I want to fill six electrons into orbitals, the filling of electrons will be as follows;

1s2 2s2 2p2.

The first four electrons are filled into the 1s and 2s levels having only one orbital each. The fifth and sixth electrons are filled into 2p orbitals. The 2p level have three degenerate orbitals. The two electrons are singly filled into each of the degenerate orbitals in accordance to Hund's rule.
