273 K

B

606 K

C

303 K

D

403 K

Answer

606 K

Explanation

Solution

USO2UO2=MO2TSO2MS2TO2=32×64×TSO2303=1\frac { U _ { \mathrm { SO } _ { 2 } } } { U _ { O _ { 2 } } } = \sqrt { \frac { M _ { O _ { 2 } } T _ { S O _ { 2 } } } { M _ { S _ { 2 } } T _ { O _ { 2 } } } } = \sqrt { \frac { 32 \times } { 64 \times } \frac { T _ { S O _ { 2 } } } { 303 } } = 1
