Increase in temperature makes the atoms speed up, and decrease in temperature makes the atoms move slower.
The primary colors are blue, red, and yellow.
Answer : When we consider the atmospheric pressure as 1 atm then according to the ideal gas equation we can find out the molar mass of any unknown by this formula ;
PV=nRT
so if the pressure increases than 1 atm then we can see from the above equation that it will result in greater value for the number of moles (n) in the above equation.
While n = m/M where m is mass of the unknown in g and M is molecular mass.
So, if pressure is higher then it will result in molar mass of unknown which is much smaller.
Answer :
(A) The rate expression will be:
(B) The average rate of the reaction during this time interval is, 0.00176 M/s
(C) The amount of Br₂ (in moles) formed is, 0.0396 mol
Explanation :
Rate of reaction : It is defined as the change in the concentration of any one of the reactants or products per unit time.
The given rate of reaction is,
The expression for rate of reaction :
<u>Part A:</u>
The rate expression will be:
<u>Part B:</u>
The average rate of the reaction during this time interval is, 0.00176 M/s
<u>Part C:</u>
As we are given that the volume of the reaction vessel is 1.50 L.
Now we have to determine the amount of Br₂ (in moles).
The amount of Br₂ (in moles) formed is, 0.0396 mol
