Atoms make up everything, so technically--everywhere.
Whenever energy is converted from one form to another, some of that energy is lost by being changed into heat.
Answer:
1.38 mol.
Explanation:
- It is known that every 1.0 mole of a molecule contains Avogadro's number of molecules (NA = 6.022 x 10²³).
<em><u>Using cross multiplication:</u></em>
1.0 mole of H₂SO₄ contains → 6.022 x 10²³ molecules.
??? moles of H₂SO₄ contains → 8.31 x 10²³ molecules.
<em>∴ The no. of moles in (8.31 x 10²³ molecules) of H₂SO₄ </em>= (1.0 mol)(8.31 x 10²³) / (6.022 x 10²³ molecules) = <em>1.38 mol.</em>
Answer:
The rate of the over all reaction is ;
![R=K[A_2]^{1/2}[B]](https://tex.z-dn.net/?f=R%3DK%5BA_2%5D%5E%7B1%2F2%7D%5BB%5D)
Explanation:
Step 1 :
fast
Step 2 :
slow
Equilibrium constant of the reaction in step 1:
....[1]
Overall reaction:

When there is a chemical reaction which taking place in more than 1 step than the rate of the over all reaction is determined by the slowest step occurring during that process;
Here step 2 is slow step, so the rate of the reaction will be;
..[2]
Putting value of [A] from [1] in [2]:
![R=k\times \sqrt{K_1\times [A_2]}\times [B]](https://tex.z-dn.net/?f=R%3Dk%5Ctimes%20%5Csqrt%7BK_1%5Ctimes%20%5BA_2%5D%7D%5Ctimes%20%5BB%5D)

K = rate constant of the reaction
The rate of the over all reaction is ;
![R=K[A_2]^{1/2}[B]](https://tex.z-dn.net/?f=R%3DK%5BA_2%5D%5E%7B1%2F2%7D%5BB%5D)
