Answer:
A. Limiting reactant is A.
B. Limiting reactant is A.
C. Limiting reactant is B.
D. Limiting reactant is B.
Explanation:
It is possible to find the limiting reactant for a reaction taking the moles of a reactant that will react and using the chemical equation find the moles of the other reactant you will need.
For the reaction:
2A + 4B → 3C
A. 2 moles A requires:
2molA×= 4moles of B
As you have 5 moles of B, <em>limiting reactant is A.</em>
B. 1,8 moles A requires:
1,8 molA×= 3,6 moles of B
As you have 4 moles of B, <em>limiting reactant is A.</em>
C. 3 moles A requires:
3 molA×= 6 moles of B
As you have just 4 moles of B, <em>limiting reactant is B.</em>
D. 22 moles A requires:
22 molA×= 44moles of B
As you have just 40 moles of B, <em>limiting reactant is B.</em>

Answer:
Rate = 0.001615 Ms-1
Explanation:
2 NO2 + F2 --> 2 NO2F
The reaction is first order with respect to NO2 and also first order with respect to F2.
The rate law is given as;
Rate = k [NO2] [ F2]
k = 1.58E-4 M-1s-1
[NO2] = 2.84 M
[F2] = 3.60 M
Rate = ?
Inserting the values into the equation, we have;
Rate = 1.58E-4 * 2.84 * 3.60
Rate = 0.001615 Ms-1
