Consider the reaction of A(g) + B(g) + C(g) =&gt; D(g) for whichthe following data were obtained:
AveGali [126]

Answer:

rate= k[A]²[B]²[C]

Explanation:

When concentration of A is increased two times ,keeping other's concentration constant , rate of reaction becomes 4 times .

So rate is proportional to [A]²

When concentration of B is increased two times , keeping other's concentration constant,rate of reaction becomes 4 times.

So rate is proportional to [B]²

When concentration of C is increased two times , keeping other's concentration constant, rate of reaction becomes 2 times.

So rate is proportional to [C]

So rate= k[A]²[B]²[C]

at what temperature in celsius would a gas have volume of 13.5 L at a pressure of 0.723 atm, if it had a volume of 17.8 L at a p
Alex

Answer:

initial temperature=-3.31^{\circ}C

Explanation:

Assuming that the given follows the ideal gas nature;

P_1=0.723atm

V_1=13.5L

T_1=?

P_2=0.612atm

V_2=17.8L

T_2=28 ^{\circ}C =273+28K=301K

mole of gass will remain same at any emperature:

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

putting all the value we get:

T_2 =269.7K =-3.31 ^{\circ} C

initial temperature=-3.31^{\circ}C
