1 answer:

5 0

Kinetics is the study of reaction rates and how they are affected. Many factors, such as concentration, pressure, temperature, and enzyme activity, can impact the rate of a reaction.

Calculate the mass of water vapour present in a room of volume 400 m3 that contains air at 27 °C on a day when the relative humi

Alex73 [517]

Answer:

Mass of water = 6251. 706g or 6.25Kg

Explanation:

Relative humidity = (actual vapor pressure/saturation vapor pressure) * 100%

Actual vapor pressure, Pw = relative humidity * saturation vapor pressure

Pw = 60% * (35.6 *0.001)atm = 0.0216atm

Note: 1mbar = 0.001atm

Using the ideal gas equation: PV=nRT; where P = Pw= 0.02136atm, V= (400

* 1000)dm^3, R= 0.082 atmdm^3/kmol, T= (27+273)K, n = number of moles

Note: 1m^3 = 1000dm^3,R is the molar gas constant.

Making n subject of the formula, n = PV/RT

n= (0.02136 * 400000)/(0.082 * 300) = 347.317 moles

Mass (g) = number of moles (n) * molar mass

molar mass of water=18g

Mass of water = 347.317 * 18 = 6251. 706g or 6.25Kg

Which statement correctly describes the relationship between thermal energy and particle movement?

Hunter-Best [27]

As thermal energy increases and there is more particle movement.

Thermal energy is the energy possessed by the system or object due to the movement of its particles.

For example kinetic energy of the particles
Higher the motion of the particles more will be the thermal energy of the system or object and vice-versa
It is also termed as heat energy of a system or object
The higher the thermal energy, the higher will be the temperature and vice versa.

So, from this, we can conclude that as thermal energy increases and there is more particle movement.
