Which of the following rate laws is correct

What can you tell from the above figure?

1. Reaction is irreversible.

2. N₂ is weakly adsorbed.

3. NO is weakly adsorbed.

4. Reaction is at equilibrium.

5. None of the above.

1. Reaction is irreversible.

2. CO₂ is weakly adsorbed.

3. Reaction is at equilibrium.

4. CO is weakly adsorbed.

5. NO is weakly adsorbed.

For a fixed concentration of NO which of the following curves describes the rate law for the case when P_NO is very very small? 

A	B
C	D
E

A is True

Similarly,

B is True

D is True

     But,

 E is True

C is false

The rate law is

and

Substituting for

     in the rate law

we obtain

 Ans:  D

Rate law suggests

Ans: B, N₂ weakly adsorbed

1)      Reaction is irreversible.
2)      CO₂ is weakly adsorbed.
