A sample of oxygen has a volume of 128 milliliter at a pressure of 500.0 mmhg calculate the volume this sample would occupy at s
leva [86]

Answer:

84.2mL

Explanation:

The following data were obtained from the question:

Initial volume (V1) = 128mL

Initial pressure (P1) = 500mmHg

Final pressure (P2) = stp = 760mmHg

Final volume (V2) =..?

Thus, the new volume of the gas can be obtained by using the Boyle's law equation as follow:

P1V1 = P2V2

500 x 128 = 760 x V2

Divide both side by 760

V2 = (500 x 128)/760

V2 = 84.2mL

Therefore, the new volume of the gas is 84.2mL

How to calculate magnitude of k
olasank [31]
Use Arrhenius equation: 
k = A*exp(-Ea/RT) 
We have: 
1.35x10^2/s = A*exp(-85600/(8.314*298.15)) 
or: A = 1.342x10^17/s 
It is a piece of cake to calculate: 
k = 1.342x10^17*exp(-85600/(8.314*348.15)) 
= 1.92x10^4/s
