Solution

The correct option is C x=2,y=1,z=2
When sulfuric acid is heated at a higher temperature then it decomposes to sulphur dioxide.

2H2SO4830C−−2SO2+2H2O+O2.

The balanced reaction between molecular iodine and sulfur dioxide is I2+SO2+2H2O120C−−2HI+H2SO4

The balanced equation of decomposition of HI is 2HI320C−−H2+I2.

Therefore, x=2,y=1,z=2.

The correct option is D.
