Suppose a two-level system is in a bath with temperature 247 k. the energy difference between the two states is 1.1 × 10-21 j. what is the probability that we will find the system in the higher energy state?

The probability of higher energy state is 0.4200.

Explanation:

Given that,

Temperature = 247 K

Energy difference between two states

We need to calculate the probability of higher energy state

Probability of

Probability of

The total probability is

Here, E₁ = lower energy state

E₂ = higher energy state

Put the value of E₁ in to the formula

Here,

Put the value into the formula

Hence, The probability of higher energy state is 0.4200.

a

explanation:

because they are cartillidge

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
