Answer:
The answer is:
Explanation:
1. The pressure of the gas increases. I think is incorrect because there is a direct proportion between number of particles and pressure, if the number of particles diminishes, then, the pressure diminishes.
2. The pressure of the gas remains the same. It's incorrect if one diminishes also the other will diminish
3. The number of collisions of gas particles decreases.
I think this is the correct one, if there are less particles, then they will interact less and the collisions will decrease.
4. The number of collisions of gas particles remains the same. It's incorrect the number of collisions could not stay the same due to the number of particles is lower.

This is an incomplete question. The complete question is:
Consider the following reaction: 2 C + D → J + 2 K .You are told that the rate of this reaction is second order overall and second order in [C]. Could any of the following be a rate-determining first step in a reaction mechanism that is consistent with the observed rate law for the reaction (note that substance Z is an intermediate)?
Answer choices
C → J + Z
C + C → K + Z
D → J + K
C + D → J + Z
Answer:
C + C → K + Z
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
![2C+D\rightarrow J+2K](https://tex.z-dn.net/?f=2C%2BD%5Crightarrow%20J%2B2K)
![Rate=[C]^x[D]^y](https://tex.z-dn.net/?f=Rate%3D%5BC%5D%5Ex%5BD%5D%5Ey)
given x = 2
Over all order = x+ y = 2
Thus y= 0
![Rate=[C]^2[D]^0](https://tex.z-dn.net/?f=Rate%3D%5BC%5D%5E2%5BD%5D%5E0)
Thus the rate determining step must use two molecules of C as that determines the order of reaction.
The only choice that fits in is C + C → K + Z
None since CO3 does not exist.
