Natural diamonds are made very deep within earth's surface where high temperatures and pressure exist naturally, thus making them much more difficult to obtain, and making them a more expensive option that Swarovski Crystal.
Answer:
Option-B (k) is the correct answer.
Explanation:
As we know the rate of reaction is given as;
Rate = k [A]ˣ
Where;
Rate = Rate of Reaction
k = rate constant
[ ] = concentration of A
x = order of reaction
So, from this equation we found that rate of reaction depends upon concentration and rate constant (k).
Now,
The rate constant is as follow,,
k = Ae^(Ea/RT)
This equation is known as Arrhenius Equation, according to this equation rate constant depends upon Temperature and Activation energy. Greater the temperature greater is the rate constant and hence greater is the rate of reaction. Or smaller the activation energy greater is the rate constant and vice versa.
The Atomic Number.

Answer:
It is difficult to prove the law of conservation of mass when a gas is produced because the gas molecules move quickly into the outside space and away
Answer:
A catalyst provides an alternative pathway for the reaction, that has a lower activation energy. ... Increasing the temperature will mean there are more particles with high energy, greater than the activation energy, so a higher chance of a successful reaction.
