zhuklara [117]3 years ago

4 0

Answer:

Physical Properties

Alkali metals are good conductors of heat and electricity while halogens are poor conductors of heat and electricity.

Only specific to Alkali metals: They are soft and can be cut by knife.

Chemical Properties

Alkali metals have 1 valence electron while halogens have 7 valence electrons.

Alkali metals react with non-metals to form ionic compounds while halogens react with non-metals to form covalent compounds.

You can also look at the trends ( melting/boiling point, reactivity) down their group.

Integrated rate law for second order unimolecular irreversible

kirill115 [55]

Answer:

The rate law for second order unimolecular irreversible reaction is

$\frac{1}{[A]} = k.t + \frac{1}{[A]_{0} }$

Explanation:

A second order unimolecular irreversible reaction is

2A → B

Thus the rate of the reaction is

$v = -\frac{1}{2}.\frac{d[A]}{dt} = k.[A]^{2}$

rearranging the ecuation

$-\frac{1}{2}.\frac{k}{dt} = \frac{[A]^{2}}{d[A]}$

Integrating between times 0 to t and between the concentrations of $[A]_{0}$ to [A].

$\int\limits^0_t -\frac{1}{2}.\frac{k}{dt} =\int\limits^A_{0} _A\frac{[A]^{2}}{d[A]}$

Solving the integral

$\frac{1}{[A]} = k.t + \frac{1}{[A]_{0} }$

What is the relationship between the temperature of an object and the motion of its particles??

ivann1987 [24]

They are directly proportional to each other, in other words, when temperature of an object increases, the motion of it's particles also increases

Hope this helps!
