Nitrogen gas and oxygen gas react according to the following equation

Chemistry
1 answer:
Paraphin [41]3 years ago
6 0

If the system is cooled, more of the products will be formed as the equilibrium shifts to the right.

Explanation:

The reaction is an endothermic reaction which absorbs heat from the environment. This is why we see energy on the reactant side.

This reaction is in equilibrium when energy is absorbed in this manner.

According to Le Chatelier's principle "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".

  • A change in temperature of an equilibrium system shifts the system to a new equilibrium point.
  • The backward reaction is favored by an increase in temperature because heat is absorbed in that step.
  • This will eventually lead to the production of more of the product.
  • Cooling the system will decrease the temperature and will favor the forward reaction.
  • If the system is cooled, more of the products will be formed as the equilibrium shifts to the right.
  • More NO gas will be produced in the process.

According to Reference Table H, what is the vapor pressure of propanone at 45°C?
makkiz [27]
If we work it out with direct proportions, the vapor pressure of propanone is 56 degrees Celsius. The atmospheric pressure is about 101 kPa. If the vapor pressure is equal to the atmospheric pressure, the substance boils. Therefore, if we hold a linear proportion, 45/56 = x/101. 56x = 101*45, x = 101*45/56 = 81. The closest choice here is (3) 70 kPa.

Next time, please provide us with Reference Table H.

Water (10 kg/s) at 1 bar pressure and 50 C is pumped isothermally to 10 bar. What is the pump work? (Use the steam tables.) -7.3
Andreyy89

Answer:

The pump work is 3451 kJ/s

Explanation:

Pump work (W) is calculated as

W = (h_f - h_i) \times \dot{m}

where

h_f is the enthalpy of water at its final state

h_i is the enthalpy of water at its initial state

\dot{m} = 10 kg/s is water mass flow

For liquids, properties are evaluated as saturated liquid. From the figure attached, it can be seen that

h_f = 762.81 kJ/kg

h_i = 417.46 kJ/kg

Replacing

W = (762.81 kJ/kg - 417.46 kJ/kg) \times 10 kg/s

W = 3451 kJ/s
