The kinetics of a gas phase reaction of the form A → Products results
Romashka [77]

It will take 21.57min for the concentration of A to reach

0.080 M if The kinetics of a gas phase reaction of the form A → Products results

The kinetic concept of gases is an easy, historically tremendous classical version of the thermodynamic conduct of gases, with which many major principles of thermodynamics had been installed. gasoline kinetics is technological know-how in the department of fluid dynamics, worried with the take a look at of motion of gases and their outcomes on physical systems. based on the principles of fluid mechanics and thermodynamics, gasoline dynamics arises from the studies of fuel flows in transonic and supersonic flights.

Unit of rate constants for

0 order reaction = M/s

1st order reaction = sec-1

2nd order reaction = M-1s-1

So, this reaction is a 0-order reaction because it's rate constant has a unit M/min

Now half-life of 0 order reaction = Ao/2K

Where Ao = initial concentration

              K = rate constant

using kinetics of a gas

Given,

Ao = 0.337M and K = 0.00781M/min

Putting all the values we get

t1/2 = 0.337/2×0.00781 min

On calculating

t1/2 =  21.57min

Law Incorporation [45]

Answer:

The transformation is of chemical energy (use the ATP molecule as a resource) which is then transformed into mechanical energy (muscle contraction) and finally transformed into thermal energy (increase in body temperature, or sweating)

Explanation:

Energy is never lost, it is always transformed, that is why energy is yielding electronic movement and expressing itself in different ways, first as chemical energy, then as mechanical energy, and lastly as thermal energy.

It is important to clarify that the energy source of all this transformation is food and energy reserves.

Nitrous oxide (n2o), or laughing gas, is commonly used as an anesthetic in dentistry and surgery. how many moles are present in
Gelneren [198K]

Answer is: 0.375 moles are present in 8.4 liters of nitrous oxide at stp.

V(N₂O) = 8.4 L.

V(N₂O) = n(N₂O) · Vm.

Vm = 22,4 L/mol.<span>
n</span>(N₂O) = V(N₂O) ÷ Vm.

n(N₂O) = 8.4 L ÷ 22.4 L/mol.

n(N₂O) = 0.375 mol.<span>
Vm - molare volume on STP.</span>
