Question

→

1. A + 2B→→→→D
The rate of formation of D in the above reaction is found experimentally to be
independent of the concentration of B
and to quadruple when the
concentration of A is doubled.

Write the rate law for the reaction​

Answer 1

[A]²

Step-by-step explanation:

Since the formation is independent of D, D is 0 order.

Since a quadruples when it is doubled it can be written as

2A^X= 4

To find the unknown power we can assume A= 1 to make the math simple. So When a = 2 (Because you doubled it) raised to X power it will equal 4

so the unknown power is 2

Making the rate law

[a]²[b]⁰

or simply just

[A]²
