Answer : The rate constant for this reaction at 384.7 K is,
Explanation :
The relation between frequency factor, rate constant and activation energy for a chemical reaction is,
where,
k = rate constant = ?
A = frequency factor =
Ea = activation energy = 12.9 kJ/mol
T = temperature = 384.7 K
Now put all the given values in this formula, we get:
Therefore, the rate constant for this reaction at 384.7 K is,
Answer:
v = 17.71 m / s
Explanation:
We can work this exercise with the kinematics equations. In general the body is released so that its initial velocity is zero, the acceleration of the acceleration of gravity
v² = v₀² - 2 g (y -y₀)
v² = 0 - 2g (y -y₀)
when it hits the stone the height is zero and part of the height of the seagull I
v² = 2g y₀
v = Ra (2g i)
let's calculate
v =√ (2 9.8 16)
v = 17.71 m / s

Answer:
Physical equilibrium is defined as the equilibrium which develops between different phases or physical properties. In these processes, there is no change in chemical composition. The following are some examples of Physical Equilibria: Solid-Liquid Equilibria. Please give me the brainliest answer?
