Calculate the work engergy gained or lost by the system when a gas expands from 35 to 55 l against a constant external presure o
1 answer:
Answer: The work energy lost by the system is -6078 Joules
Explanation:
According to first law of thermodynamics:
=Change in internal energy
q = heat absorbed or released
w = work done or by the system
w = work done by the system= {Work is done by the system as the final volume is greater than initial volume and is negative}
where P = pressure = 3 atm
= change in volume = (55-35) L = 20 L
w =
{1Latm=101.3J}
Thus work energy lost by the system is -6078 Joules

Answer:
The simplified expression for the fraction is
Explanation:
From the given information:
O3* → O3 (1) fluorescence
O + O2 (2) decomposition
O3* + M → O3 + M (3) deactivation
The rate of fluorescence = rate of constant (k₁) × Concentration of reactant (cO)
The rate of decomposition is = k₂ × cO
The rate of deactivation = k₃ × cO × cM
where cM is the concentration of the inert molecule
The fraction (X) of ozone molecules undergoing deactivation in terms of the rate constants can be expressed by using the formula:
since cM is the concentration of the inert molecule
