How does a temperature increase cause the rate of a reaction to increase?
A. It increases the kinetic energy of the molecules.
B. It decreases orientation requirements of the molecules.
C. It increases the equilibrium constant for the reaction.
D. It decreases the activation energy of the reaction.
Answer:
B
Explanation:
"The temperature increases cause the rate of a reaction to increases the kinetic energy"
What is rate of reaction?
The reaction rate, also known as the rate of reaction, is the rate for which a chemical reaction occurs, and is proportional to increase in product concentration per unit time and the reduction in reactant concentration per unit time. The rate of reaction varies greatly.
What is kinetic energy?
An object's kinetic energy is the energy it has as a result of its motion. It is the amount of work required to push a body of a given mass from rest to a certain velocity. The body keeps its kinetic energy gained during acceleration unless that speed changes.

What is the percentage by mass of chromium in sodium dichromate (VI) Na2
Cr2
O7
?
Answer:
39.7%
Explanation:
To obtain the percentage composition of chromium (Cr) in Na₂Cr₂O₇, do the following:
Molar mass of Na₂Cr₂O₇ = (23×2) + (52×2) + (16×7)
= 46 + 104 + 112
= 262 g/mol
Mass of Cr in Na₂Cr₂O₇ = 2 × 52 = 104 g
Percentage composition of Cr = mass of Cr / Molar mass of Na₂Cr₂O₇ × 100
= 104 / 262 × 100
= 39.7%
Thus, the percentage composition of chromium (Cr) in Na₂Cr₂O₇ is 39.7%

Which of the following is true?
A)If we know that a reaction is an elementary reaction, then we know its rate law.
B)The rate-determining step of a reaction is the rate of the fastest elementary step of its mechanism.
C)Since intermediate compounds can be formed, the chemical equations for the elementary reactions in a multistep mechanism do not always have to add to give the chemical equation of the overall process.
D)In a reaction mechanism, an intermediate is identical to an activated complex.
E)all of these statements are true.
Answer:
If we know that a reaction is an elementary reaction, then we know its rate law.
Explanation:
An elementary reaction is a reaction that takes place in one reactive encounter. This means that the two species interact in a single step to give the products.
If two reactants interact in a single step to yield the products then we can easily deduce the rate law from the reaction equation.
For instance, For the reaction;
2A + B → C
The rate law is
rate = k[A]²[B].
If the reaction is an elementary reaction and the equation of the reaction is balanced, then we can deduce the rate law from the balanced reaction equation.
The pressure 15.0 m under water is 248 kPa.
What is this pressure in torr
Answer:
1860 torr
Explanation:
In order to convert from kPa to torr, we are going to use the following conversion factor:
1 kPa = 7.5 torrNow we multiply 248 kPa with this factor so that the kPa units cancel each other and only the torr units remain:
248 kPa * [tex]\frac{7.5torr}{1kPa}[/tex] = 1860 torrThis means that the answer is 1860 torr.

What is the activation energy of a reaction?
A. The energy that is given off when a reaction happens
B. The kinetic energy of the colliding molecules
C. The speed at which the molecules must be moving in order to
react
D. The energy the molecules must have in order to react
SUBMIT
Answer:
D i took it aswell
Explanation:
The energy the molecules must have in order to react. Hence, option D is correct.
What is activation energy?Activation energy is the sufficient amount of energy necessary to initiate a chemical reaction.
It can also be said as the minimum amount of energy needed to energize molecules or atoms so that they can undergo a chemical reaction or transformation.
Hence, the energy the molecules must have in order to react.
