Heyyy how’s your day!!!???
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:
The left side of the equation i.e ∆p=MVo should be used
Explanation:
Momentum is the product of mass and velocity or the quantity of motion an object has.
Impulse is the change in momentum
If P is the momentum
If M is the mass of the object
Vo is the velocity of the object
∆p=P2-P1
Since the wall is stationary, P1 = 0
The momentum of the object itself is P2
Therefore, ∆p=P2
Since P2=MVo
∆p=MVo
Light shows duality i.e it shows properties of both particle as well as wave.
Answer:
true
