Question

For a chemical reaction A + B → Product, the order is 1 with respect to A and B . Rate mol L - 1 S - 1 [A] mol L - 1 [B] mol L - 1 0 . 10 20 0 . 5 0 . 40 x 0 . 5 0 . 80 40 y What is the value of x and y ?

TestHub · Accepted Answer

To determine the values of x and y, we can use the information provided and the rate expression for the given reaction, which is first order with respect to both A and B:

Rate $r = K [A]^{1} [B]^{1}$

$0.1 = K (20)^{1} (0.5)^{1} \dots (i) 0.40 = K (x)^{1} (0.5)^{1} \dots (ii) 0.80 = K (40)^{1} (y)^{1} \dots (iii)$

From (i) and (ii)

$x = 80$

From (i) and (iii)

$y = 2$

Rate $mol L^{- 1} S^{- 1}$	[A] $mol L^{- 1}$	[B] $mol L^{- 1}$
$0.10$	$20$	$0.5$
$0.40$	$x$	$0.5$
$0.80$	$40$	$y$
