`aK_(2)Cr_(2)O_(7)+bKCl+cH_(2)SO_(4)rarrxCrO_(2)Cl_(2)+yKHSO_(4)+zH_(2)O`
The above equation balances when

A

`a=2, b = 4 ,c = 6 and x = 2 , y = 6 , z = 3 `

B

`a=4, b = 2 ,c = 6 and x = 6 , y = 2 , z = 3 `

C

`a=6, b = 4 ,c = 2 and x = 6 , y = 3 , z = 2 `

D

`a=1, b = 4 ,c = 6 and x = 2 , y = 6 , z = 3 `

Text Solution

Verified by Experts

The correct Answer is:
D
`K_2Cr_2O_7 + 2H_2SO_4 rarr2KHSO_4+2CrO_3+H_2O`
`2KCl+H_2SO_4rarr2KSO_4+2HClxx2`
`{:(CrO_3+2HClrarrCrO_2Cl_2+H_2O"]"xx2),(bar(K_2Cr_2O_7+4KCl+6H_2SO_4rarr2CrO_2Cl_2+6KHSO_4+3H_2O)):}`
