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

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
