Question

q. If a is degree of dissocliation, then the total number
of moles for the reaction starting with 1 mole of HI
2HI = H2 + I2 will be

(1) 1
(2) 1 - a
(3)2
(4)2-a​

Answer 1

Answer:

Explanation:

Given that,

2 HI GIVE H 2 +I 2

 2*1             0      0  

 2(1-a)          a      a  

so,

i= (2- 2a+a+a)/2

i= 2/2

i=1
