Rate $= k[B]^3$

Vedclass · Answer

Let the rate law be $r\,=\,k\,[A]^x[B]^y$

Divide $(3)$ by $(1)$ $\frac{{0.10}}{{0.10}}{\mkern 1mu} \, = \,{\mkern 1mu} \frac{{{{[0.024]}^x}{{[0.035]}^y}}}{{{{[0.012]}^x}{{[0.035]}^y}}}$

$	herefore \,1\, = \,{[2]^x},\,x\, = \,0$

Divide $(2)$ by $(3)$ 

$\frac{{0.80}}{{0.10}}{\mkern 1mu} \, = \,{\mkern 1mu} \frac{{{{[0.024]}^x}{{[0.070]}^y}}}{{{{[0.024]}^x}{{[0.035]}^y}}}$

$	herefore $ $8 = \,{(2)^y},\,y\, = \,3$

Hence rate equation ,

$R\,=\,k[A]^0\,[B]^3$ $=\,k[B]^3$

Expt. No.	$(A)$	$(B)$	Initial Rate
$1$	$0.012$	$0.035$	$0.10$
