The reaction A + 2B → products has been found to have the rate law, rate = k[A][B]2. While holding the concentration of A constant, the concentration of B is tripled. Predict by what factor the rate of reaction increases

9 times

Explanation:

A + 2B → products

rate = k[A][B]2

While holding the concentration of A constant, the concentration of B is tripled. Predict by what factor the rate of reaction increases.

We can achieve this by given the concentration dummy values.

Assuming the following values (Any number works, or letters);

concentration of A = 1

Concentration of B = 2

rate = k[A][B]2

rate = k (1)* (2)^2

rate = k 4 i

When Conc of B is tripled;

Concentration of B = 3 * 2 = 6

rate = k[A][B]2

rate = k (1) * (6)^2

rate = k 36 ii

Comparing both rates;

The ratio is 36: 4, upon simplifying = 9 : 1

This means the factor increases by 9 times

girl imma just put my comment here because i need a couple point okurrttt

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
