Answer:
HCl is not a catalyst because these are not used up during the chemical reactions.
Explanation:
Hello there!
In this case, according to the performed experiments, it is possible for us to realize that HCl cannot be a catalyst for this reaction because it is used up during the reaction. This is explained by the fact that catalyst are able to return to the original form once the reaction has gone to completion; this is the example of palladium in the hydrogenation or dehydrogenation of hydrocarbons depending on the case. Moreover, we know that the catalysts increase the reaction rate because they decrease the activation energy of the reaction and therefore the student observed such increase.
Best regards!
The correct answer to this question is "5." the oxidation number of cl in ClO3 will be a positive 5 because oxygen is naturally a -2 charge. times that by three and then account for the negative charge of the CLO3- ion.
Answer: the speed at which products form
Explanation:
Rate of a reaction is defined as the speed at which a chemical reaction proceeds. It is often expressed in terms of the concentration of a reactant that is consumed in a unit time or the concentration of a product that is formed in a unit of time.
For a general reaction :
![Rate=-\frac{d[A]}{dt}](https://tex.z-dn.net/?f=Rate%3D-%5Cfrac%7Bd%5BA%5D%7D%7Bdt%7D)
or ![Rate=+\frac{d[B]}{dt}](https://tex.z-dn.net/?f=Rate%3D%2B%5Cfrac%7Bd%5BB%5D%7D%7Bdt%7D)
where d[A] = change in concentration of reactant A
d[B] = change in concentration of product B
dt = time interval
Answer:The amount of product will be higher than the amount of substrate at equilibrium
Explanation:
Recall that the equilibrium constant K depends on the amounts of reactants and products present in the system at equilibrium.
Considering the equation; K = [X]/[Y], as the concentration of X increases above that of Y, the equilibrium constant K becomes very high, hence the answer above.
In a liquid, particles are close together but can move in any direction. They won't keep a definite shape like solids do.
