In the reaction
` K_2 Cr_2 O_7 +XH_2 SO_4 +YSO_2 to K_2 SO_4 +Cr_s(SO_4)_3 +ZH_2 O`
X,Y,Z are

A

1,3,1

B

4,1,4

C

3,2,3

D

2,1,2

Text Solution

Verified by Experts

The correct Answer is:
A
the balanced equation is
` K_2 Cr_2 O_7 +H_2 SO_4 +3SO_2 to K_2 SO_4 +Cr (SO_4)_3 +H_2 O`
therefore X,Y, and Z the coefficeints of `H_2 SO_4 , SO_2` and `H_2O` Respectively are 1 ,3,1
