Your answer to that question is Fand N
The correct answer for this question is activation energy, orientation, and frequency.
The rate of a chemical reaction is directly related to its activation energy because the higher the activation energy the lower is the rate of reaction as we know the reaction only proceed when the reactants have absorbed the enough heat energy to reach the transition state. Thus activation energy determines the rate of reaction.
The orientation of the particles is also very important as we know that the reaction between the two reactants only occur when they collide with proper orientation in time the greater the probability of the collision the greater is the rate of reaction and also the number of collisions also determines the rate of reaction.
The frequency is directly proportional to the rate of chemical reaction as the frequency of the collision increases the rate of the chemical reaction also increases.

Answer:
polymerization
Explanation:
Student is explaining the process of formation of a polymer and the process is called polymerization.
Polymer is made up of joining repeating units. The repeating units are called monomers.
Properties of the polymer is determined by the structure of monomer molecule.
For example, consider a well-known polymer Teflon.is made by the polymerization of tetrafluoroethane.
Thus, the student is explaining polymerization.
Answer:
∇T = 51.68°C
Explanation:
Mass = 150g
Heat Energy (Q) = 1.0*10³J
Change in temperature ∇T = ?
Q = mc∇T
Q = heat energy
M = mass
C = specific heat capacity of the gold = 0.129j/g°C
∇T = change in temperature
Q = Mc∇T
1.0*10³ = 150 * 0.129 * ∇T
1000 = 19.35∇T
Solve for ∇T
∇T = 1000 / 19.35
∇T = 51.679°C = 51.68°C
The change in temperature of gold was 51.68°C
