C bc it only has red in it
Answer:
The rate of the reaction will increase by a factor of 9.
Explanation:
Hello,
In this case, considering the given second-order reaction, whose rate law results:
![r=k[A] [B]^2](https://tex.z-dn.net/?f=r%3Dk%5BA%5D%20%5BB%5D%5E2)
We easily infer that at constant concentration of A but tripling the concentration of B, we are going to obtain the following increasing factor while holding the remaining variables constant:
![Increase\ factor=\frac{r_{final}}{r_{initial}} =\frac{k[A][3*B]^2}{k[A][B]^2} =\frac{3^2}{1} \\Increase\ factor=9](https://tex.z-dn.net/?f=Increase%5C%20factor%3D%5Cfrac%7Br_%7Bfinal%7D%7D%7Br_%7Binitial%7D%7D%20%3D%5Cfrac%7Bk%5BA%5D%5B3%2AB%5D%5E2%7D%7Bk%5BA%5D%5BB%5D%5E2%7D%20%3D%5Cfrac%7B3%5E2%7D%7B1%7D%20%5C%5CIncrease%5C%20factor%3D9)
Best regards.
Enzymes are organic catalysts
and catalysts generally increase rate of reaction by lowering activation energy
C is the answer
An ion-dipole force is a type of intermolecular force in which forces of attraction or repulsion occur between neighboring ions, molecules or atoms.
The correct options are as follows:
1. A.
A synthesis reaction is a type of reaction in which two or more reactants combine together to form only one product. Synthesis reaction always release energy in form of light and heat, therefore, they are usually exothermic reactions. In the option given in A, nitrogen and nitrogen combine together to form ammonia; this is a synthesis reaction.
2. D
A radioactive half life refers to the amount of time it will take for half of an original radioactive isotope to decay.
In the question given above, the half life of the element is 1000. Thus, in 1000 years only half of the original amount will remain. In another 1000 years only 1/4 of the original amount will remain and in another 1000 years only 1/8 of the original amount will remain. Therefore, it will take 3 half lives before 1/8 of the original sample remain.<span />
