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.
given x = 2
Over all order = x+ y = 2
Thus y= 0
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
Cell theory was discovered from the scientist
First, we discuss the given values. E₀ cell is the reduction potential of the cell. This indicates the tendency of a given substance to be reduced. Next, ΔG is the Gibbs free energy, and a negative Gibbs free energy indicates the likelihood of a reaction taking place. Therefore, for a spontaneous reaction, ΔG will be negative and E₀ cell is positive.
The second option is correct.
