For the reaction,\[{{H}_{2}}(g)+B{{r}_{2}}(g)\xrightarrow{{}}2HBr(g)\] The experimental data suggestsrate\[=k\,[{{H}_{2}}]\,{{[B{{r}_{2}}]}^{1/2}}\] The order of the reaction is
A) \[\frac{1}{2}\]
B) \[1\]
C) \[3\]
D) \[\frac{3}{2}\]
E) None of these
Correct Answer:
D
Solution :
Order of the reaction\[=1+\frac{1}{2}\]\[=\frac{3}{2}\]
