The gas phase reaction between hydrogen and iodine is proposed to occur as follows:.....step 1.....fast:......I2 2 I.....step 2.....slow:....H2 + 2 I 2 HI(1) What is the equation for the overall reaction? Use the smallest integer coefficients possible. If a box is not needed, leave it blank.

Respuesta :

Answer:

[tex]2I[/tex] will cancel out and the overall reaction  will be

       [tex]I2 + H2[/tex]   →   [tex]2HI[/tex]  

Explanation:

The gas phase reaction between hydrogen and iodine is proposed to occur as follows

Step 1  fast       [tex]I2[/tex] ⇄ [tex]2I[/tex]

step 2 slow      [tex]H2 + 2I[/tex] ⇄ [tex]2HI[/tex]

The overall reaction for these step reaction will be

       [tex]I2 + H2[/tex]   →   [tex]2HI[/tex]
