Given the following balanced equation, determine the rate of reaction with respect to [O2]. If the rate of formation of O2 is 7.

murzikaleks [220]

Answer: The rate of the loss of $O_3$ is 0.52M/s

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

The rate in terms of reactants is given as negative as the concentration of reactants is decreasing with time whereas the rate in terms of products is given as positive as the concentration of products is increasing with time.

$2O_3(g)\rightleftharpoons 3O_2(g)$

Rate of disappearance of $O_3$ = $-\frac{1d[O_3]}{2dt}$

Rate of formation of $O_2$ = $+\frac{1d[O_2]}{3dt}$

$-\frac{1d[O_3]}{2dt}=+\frac{1d[O_2]}{3dt}$

Rate of formation of $O_2$ = $7.78\times 10^{-1}M/s$

Thus Rate of disappearance of $O_3$ = $\frac{2d[O_2]}{3dt}=\frac{2}{3}\times 7.78\times 10^{-1}M/s=0.52M/s$

A mixture of benzoic acid and naphthalene was dissolved in tert-butyl methyl ether and the resulting solution was extracted with

Llana [10]

Answer:

C₆H₅COOH Benzoic Acid

Explanation:

Here we are using the extraction method to separate benzoic acid from naphtalene in the ether solution by reacting it with the base sodium bicarbonate to produce the salt sodium benzoate ( naphtalene remains in the organic layer ) .

The sodium benzoate is completely soluble in the aqueous layer being a salt, and reacts with hydrochloric acid ( again an acid base reaction ) which precipitates the benzoic acid since the it is insoluble in water hence separating it.
