Q1.Consider the reaction
2A+3B------> 4C + 5D
In the above reaction A and B are reactants and C and D are products. If one of each A and B are reacted then:
1)2.25 mole of B is formed
2)1.6 mole of D is formed
3)0.33 mole of A are left after complete reaction
4)1.33 mole of C is formed
The correct choice is
A)1 and 2
B) 2, 3 and 4
C)1,3 and 4
D) 1, 2 and 4
Answers
Explanation:
Given:
2A+3B------> 4C + 5D
To find:
Correct statements among the given options.
Solution:
First of all, we need to identify the limiting reagent.
So, as per reaction, 2 moles of A reacts with 3 moles of B.
But only 1 mole of A and B is given:
So, 1 mole of A will react with 3/2 × 1 = 1.5 mole of B.
Hence , B is limiting reagent. Reaction will occur w.r.t to B only.
Now, continue with stoichiometry!
3 moles of B form 4 moles of C
=> 1 mole of B forms 4/3 × 1 = 1.33 moles of C.
____________________
3 mole of B form 5 moles of D
=> 1 mole of B forms 5/3 × 1 = 1.6 moles of D.
____________________
3 moles of B reacts with 2 moles of A
=> 1 mole of B react with 2/3 = 0.67 mole of A
=> So, amount of A left = 1 - 0.67 = 0.33 moles .
So, statement 2, 3, 4 are correct.
Option D) is correct.
