Answer:
Average acceleration = - 2 m/s^2
Explanation: Have a nice day
C or A. I can’t decide tho. I know most def it’s gotta be one of them two.
Answer:
<em>Rate constants are temperature dependent.</em>
<em></em>
Explanation:
Reaction rate is used to quantify the rate of chemical reaction. There is a relationship between the reaction rate and the half-life of the reaction and the Gibbs free energy of activation, and the reaction rate is temperature dependent according to the equation.
For a reaction shown below
a A + b B ⇒ c C
The rate of reaction of the reaction is given by
where k(T) is the reaction constant, which is seen to be dependent on the temperature of the reaction.
Also, k(T) is numerically equal to
where
r = reaction rate
A = pre exponential factor
= Activation energy
R = gas constant
T = temperature
and m and n are experimentally determined partial orders in [A] and [B]
Answer:
1) Increase
2) Decreases
3) increases
4) Increase
Explanation:
These questions can only be answered by considering the principle which states that, "When a constraint such as a change in concentration, pressure or volume is imposed on a reaction system in equilibrium. The system will readjust itself in order to annul the constraint."
Now, if more reactants are added, the equilibrium position will shift towards the right, If more products are added, the equilibrium position will shift to the left.
Similarly, the removal of H2S causes the O2 concentration to increase since the equilibrium position now shifts to the left.
Also, addition of O2 causes H2S to be removed as the equilibrium moves to the right.
Answer:
The reaction involved in a campfire (burning of wood) includes:
Explanation:
We can clearly find here that when wood burns in presence of oxygen, there is a loss of mass in the form of gaseous products. Thus, in this case, the law of conservation of mass does not come true.
I support Lisa’s statement but there is a fact associated with the law of conservation of mass. The law stands true only when there is a definite mass of the reactants and products mentioned.
