Question

Now the container is heated due to which A changes according to the reaction nA=An. After the end of the reaction the vapour density was found to be 40 and it is known that 66.6% of A is converted in to product the find the value of n

Answer 1

Answer:

Explanation:

LOOK , 66.6% can be stated as 2/3 for calculation convenience

now, the formed mixture would have unreacted A and formed product .

so AS vapour density is given 20 of A them molar mass is 40 so as given 2/3 reacted and 1/3 remained unreacted so mixture would sum up in weight as( 40/3 + 40*n*2/3n )/ 1/3+2/3n +80

which sums out to be n=4
