NEETChemistrySome Basic Concepts of Chemistry
Given below are two statements: Statement-I : (2 ~A +3 ~B C ) ( 4 3 ) moles of ' (C ) ' are produced when 3 moles of ' (A ) ' and 4 moles of ' (B ) ' are added. Statement-II : 'A' is limiting reagent for the given data. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- AStatement-I and II both are correct.
- BStatement-I is correct while II is incorrect.
- CBoth Statement-I and II are incorrect.
- DStatement-I is incorrect and II is correct.
Correct answer
D. Statement-I is incorrect and II is correct.
Step-by-step solution
Statement-I: "4/3 moles of 'C' are produced when 3 moles of ' (A ) ' and 4 moles of ' (B ) ' are added." - From the balanced equation, 2 moles of (A ) require 3 moles of (B ). - We have 3 moles of (A ), so 4.5 moles of (B ) are required, but only 4 moles of (B ) are available. - (B ) is the limiting reagent. - Using 4 moles of B , the moles of C produced: ( 1 3 4= 4 3 ) moles of C. Statement-II: " A is the limiting reagent for the given data." Since B is the limiting reagent, Statement-II is incorrect.
