Answer to Question #127608 in General Chemistry for Bereket

Question

In a laboratory experiment,the reaction of 3.0 mol of H2( hydrogen molecule) with 2.0 mol of I2(iodine molecule) produces 1.0 mol of HI.

Determine the theoretical yield in grams and the percent yield for this reaction​

Answer 1

H₂ + I₂ ----------> 2HI

2 Mole of H₂ React With 2 Mole of I₂ And Gives 4 Mole of HI .

So , I₂ is limiting Reagent and Completly Cosume ....................

So , 4 Mole of HI formed By 2 Mole of I₂ .

Theoritical Mole of HI = 4 Mole . ANSWER .

Experimental Mole of HI = 1 Mole.

% yield = Experimental Mole * 100 / Theoritical Mole = 1 * 100 / 4 = 25% ANSWER.
