Answer:
<em>What quantity dictates the speed of a reaction?</em> The activation energy
Explanation:
According to the collision theory, when molecules collide, they must overcome an energy barrier for the reaction to take place. This energy, known as activation energy, is represented by the difference in energy between the initial state and the transition state. The higher the activation energy, the slower the reaction. That's why catalysts reduce the activation energy to accelerate the reaction.
Answer:
Explanation:
According to the law of mass action:-
The rate of the reaction is directly proportional to the active concentration of the reactant which each are raised to the experimentally determined coefficients which are known as orders. The rate is determined by the slowest step in the reaction mechanics.
Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.
The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.
From the reaction given that:-
The expression for the rate is:-
![r=k[P]^2](https://tex.z-dn.net/?f=r%3Dk%5BP%5D%5E2)
Given that;- k= 
/Ms
[P] = 
M
Thus,
B. Unless you melt the solid the solid will hold its form
Looking for evidence entails careful study. The answers to the question is below;
<h3>Evidence and Fact finding</h3>
The crime that Mr. Fraser describes is drive-by killing.
The police select their suspect by the act of showing pictures to one of the teenagers and thereafter they the suspect out, the suspect the saw that shoot the father.
The fact was that there was no evidence since they did not find the gun and the car used in the crime was not identified. Even the suspect vehicle (shooter) was not identified also.
The approximate figure is about 252 out of 367 cases of wrongful conviction have been identified. That is 69% of DNA exonerations. Others about 250-285 cases.
The National Registry of Exonerations has stated that about 450 non-DNA-based exonerations where there was eyewitness misidentification. That is about 3 quarters have eye witness testimonies.
Reconstructive memory is simply known as the act of remembering that involves the reproduction of an experience or event that is known to be partially stored in memory before.
Fraser challenged the judge to go out and inspect the crime scene themselves.
The outcome of the challenge was that the judge thereby granted the retrial for Francisco Carrillo and thus released him so he can prepare his defense before the prosecution day.
Mr. Fraser suggested that people learn to be more effective with how they handle things or situations so as to get the right evidence and also that people be more cautious about how true some eyewitness testimonies may be.
