A small bubble rises from the bottom of a lake where the temperature and pressure are 4.0 C and 3.0 atm, to the water’s surface,
Varvara68 [4.7K]

Answer:

The final volume of the bubble is 7.13 mL.

Explanation:

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 3 atm

P_2 = final pressure of gas = 0.95 atm

V_1 = initial volume of gas = 2.1 mL=0.0021 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 4^oC=273.15+4K=277.15 K

T_2 = final temperature of gas = 25^oC=273.15+25 k=298 .15 K

Now put all the given values in the above equation, we get:

\frac{3 atm\times 0.0021 L}{277.15 K}=\frac{0.95 atm\times V_2}{298.15 K}

V_2=\frac{3 atm\times 0.0021 L\times 298.15 K}{277.15 K\times 0.95 atm}=0.00713 L = 7.13 mL

The final volume of the bubble is 7.13 mL.

Consider the reaction and its rate law.
BaLLatris [955]

The order with respect to A is 2

The order with respect to B is 0.

The overall reaction order is 2.

<u>Explanation:</u>

The rate of chemical equation is represented by its rate equation. Here the rate equation of the given chemical reaction is

rate=k[B]^2

Here k represents the rate constant .

Order of the reaction with respect to its individual reactants is represented by the power of the the reactants in the rate equation.

Here the power of the reactant A is 0 and the power of reactant B is 2.

Hence the order with respect to A is 0 and order with respect to B is 2.

The overall order of the reaction is given by the sum of the powers of the reactants in the rate equation.

Hence the total order=2+0=2
