Which Metal is the Most Reactive Based on Displacement Reactions?

AI Thread Summary
The discussion centers on determining the reactivity of metals A, B, C, D, and E based on a displacement reaction matrix. The matrix indicates that a "+" signifies a reaction, while a "-" indicates no reaction, allowing for comparisons of reactivity. Initial conclusions suggest that metal E is the most reactive, followed by A, C, B, and D as the least reactive. However, contradictions arise when analyzing the relationships, particularly between metals A and B, leading to confusion about the validity of the question. The thread highlights the complexity of interpreting reactivity from the provided data.

Arrange the following metals A,B,C,D and E according to increasing reactivity out of the information
given above. Use The Symbol of greater than (>) in indicating that one metal is more reactive than the other. Ex A>B>E means metal A is more reactive than B and B is more reactive than E.

Dont know were to start...
i just know that E + AX = There is a reaction where E > A etc.

What information is this? What do the entries (+,-) in this matrix represent?
 
+ means that there is a reaction
- means that there's no reaction

and my diagram is a table... and sorry for that, can't skip it

If a metal A displace out another metal B from another metal's solution (BX), then this means that metal A is more reactive than metal B.

From the first row of the table, we can get A>B, A>C, A>D, A>E.
Then, from the second row, we get, B>A and B>C.
For the third row, C>A, C>B and C>D,
From the 4th row, we can conclude that metal D is the least reactive among the 5 metals.
5th row, E>A, E>B, E>C, E>D.

However, I think there is something wrong with this question, since we get A>B, and B>A, (and many other contradictions) which only one of them can be true.

Can you please check back the question? Thanks.:smile:
 
Thread 'Confusion regarding a chemical kinetics problem'
TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
