The longer the reaction time is, the the reaction rate is. Reaction time is to reaction rate.

Answer:

False.

Explanation:

Rate of reaction  also depends on the number of collision that is being happening in reacting molecules. So concentration of the reactants is also important to decide the rate of reaction.

The rate of reaction is dependent on the concentration as well.

As the concentration of reactants decreases with time number of collisions also decreases .

Answer:

From your question you tried to compare reaction rate and time taken(reaction time)

The rate of a reaction is inversely proportional to the time taken(reaction time)

Explanation:

Reaction rate is said to be the decrease in concentration of the reactant or the increase in the concentration of the product per unit time. Reaction rate measures how fast the reactant is used up or how fast the product is formed.

For a given reaction like

Mg(s) + O2(g) → 2MgO(aq)

The reaction rate is derived by measuring how fast the concentration of Mg and O2 decreases or how fast the concentration of MgO increases. Mathematically reaction rate can be expressed as

Reaction rate = Δconcentration/ ΔTime

Reaction rate can be affected by various factors like temperature, reactant concentration and particle size of a solid reactant.   Increasing temperature, and increasing reactant concentration increases reaction rate. Decreasing particle size of the solid reactant also increase reaction rate.  The collision theory also shed more light on the rate of reaction. How fast the individual molecules of the reactant collide also affect the reaction rate.

The reaction time is the time taken for the reactant to form product. The reaction time is the time taken for the reaction to start and stop. The longer the reaction time, the slower the reaction rate. Fast reaction have short reaction time.

The rate of a reaction is inversely proportional to the time taken(reaction time)

1.72 moles of NOCI were placed in a 2.50 L reaction chamber
elena-14-01-66 [18.8K]

The equilibrium constant, Kc=0.026

<h3>Further explanation</h3>

Given

1.72 moles of NOCI

1.16 moles of NOCI  remained

2.50 L reaction chamber

Reaction

2NOCI(g) = 2NO(g) + Cl2(g).

Required

the equilibrium constant, Kc

Solution

ICE method

   2NOCI(g) = 2NO(g) + Cl2(g).

I    1.72

C   0.56           0.56         0.28

E   1.16              0.56         0.28

Molarity at equilibrium :

NOCl :

\tt \dfrac{1.16}{2.5}=0.464

NO :

\tt \dfrac{0.56}{2.5}=0.224

Cl2 :

\tt \dfrac{0.28}{2.5}=0.112

\tt Kc=\dfrac{[NO]^2[Cl_2]}{[NOCl]^2}\\\\Kc=\dfrac{0.224^2\times 0.112}{0.464^2}=0.026

1)Define potential Energy.
Margarita [4]

1. Potential Energy is stored energy a object has when it's not moving.

2. Potential Energy is it's highest on the first stage because as you see the roller coaster is bout to go down the tract which is going to higher the kinetic energy and lower the potential energy.

3. Kinetic Energy is the amount of energy a object has when it's in motion or moving.

4. Kinetic Energy is it's highest in the third stage after it's gone down the tract and potential energy fully decreased and it's at zero.

Remember that potential energy is stored energy so when a object is not moving in this case the roller coaster isn't moving on the first stage when its bout to go down the roller coaster. Kinetic energy is the amount of energy a object has when it's in motion so in this case the third stage would have the highest example of Kinetic energy because it's fully in motion and has no potential energy.
