A two-state system is in an environment at temperature 500 K. The energy of state 1 is 4.1e-20 J, and the energy of state 2 is 5
katovenus [111]

Complete Question

A two-state system is in an environment at temperature 500 K. The energy of state 1 isE_1=4.1e-20 J, and the energy of state 2 is E_2= 5.7e-20 J. Let P(1) be the probability of finding the system in state 1, and be the probability of finding the system in state 2. What is the ratio P(2)/P(1)

Answer:

 X=0.0984

Step-by-step explanation:

From the question we are told that:

Temperature T=500 K

Energy of state 1 E_1=4.1e-20 J,

Energy of state 2 is E_2= 5.7e-20 J

Generally the equation for Probability of finding the system in state is mathematically given by

 P(1)=e ^{\frac{-E_1}{KT}}

Therefore

For Probability of finding the system in state 1 P(1)

 P(1)=e ^{\frac{-E_1}{KT}}

Where

   K is Boltzmann constant

   K=1.38*10^{-23}

 P(1)=e ^{\frac{-(4.1e-20 J)}{1.38*10^{-23}*500}}

For Probability of finding the system in state 1 P(2)

 P(2)=e ^{\frac{-(5.7e-20 J)}{1.38*10^{-23}*500}}

Generally the equation for The Ratio of P(2) and P(2) is mathematically given by

 X=\frac{P(2)}{p(1)}

 X=e ^{\frac{E_1-E_2}{KT}}

 X=e ^{\frac{-(4.1-5.7)e-20 J)}{1.38*10^{-23}*500}}

 X=0.0984
