For the hypothetical reaction: A + B ---> 2C, write an expression that relates the disappearance of A and B to the appearance of C. You can use the word delta instead of the symbol .

Respuesta :

Answer:

Rate expression has been given below

Explanation:

According to the given equation, 1 molecule of A reacts with 1 molecule of B and produces 2 molecules of B at a time.

So, rate of disappearance of both A and B are one half of rate of appearance of B

Hence rate expression can be represented as:

[tex]Rate=\frac{-\Delta [A]}{\Delta t}=\frac{-\Delta [B]}{\Delta t}=\frac{1}{2}\frac{\Delta [C]}{\Delta t}[/tex]

where [tex]\frac{-\Delta [A]}{\Delta t}[/tex] is rate of disappearance of A, [tex]\frac{-\Delta [B]}{\Delta t}[/tex] is rate of disappearance of B and [tex]\frac{\Delta [C]}{\Delta t}[/tex] rate of appearance of C
