<h3>Answer;</h3>

Large

If a reaction is exothermic and produces large quantities of heat reaching equilibrium, its equilibrium constant will be large.

<h3>Explanation;</h3>

Chemical equations may either be exothermic or endothermic based on the energy changes in the reaction. Exothermic reactions are those reactions that loose heat energy to the surrounding, therefore the enthalpy change in these reactions is negative. Endothermic reaction on the other hand are those reactions in which energy is absorbed from the reaction thus their enthalpy is positive.
Chemical equilibrium in chemical reactions occurs when the rate of forward reaction is equal to the rate of reverse reaction. Equilibrium constant is the value of the chemical reaction quotient when the equilibrium of a reaction is achieved.
If a reaction is exothermic and produces large quantities of heat in order to reach equilibrium then the equilibrium constant will be large.

The equilibrium constant will be lowered and the equilibrium will shift to the left if the heat being produced is not removed.

At which position would a person on earth see the entire lighted half of the moon?

Gemiola [76]

The best position for the person would be outside, under a clear sky, standing up. He should do it sometime between sunset and sunrise, from a day before until a day after the moment of Full Moon.

How much heat is removed from 60 grams of steam at 100 °C to change it to 60 grams

Harrizon [31]

Answer:

45200J

Explanation:

Given parameters:

Heat of vaporization of water = 2260J/g

Mass of steam = 20g

Temperature = 100°C

Unknown:

Energy released during the condensation = ?

Solution:

This change is a phase change and there is no change in temperature

To find the amount of heat released;

H = mL

m is the mass

L is the latent heat of vaporization

Insert the parameters and solve;

H = 20g x 2260J/g

H = 45200J

A wheel starts from rest and rotates with constant angular acceleration to reach an angular speed of 11.2 rad/s in 3.07 s. (a) f

Hitman42 [59]

(a) The angular acceleration of the wheel is given by
$\alpha = \frac{\omega_f - \omega_i }{t}$
where $\omega_i$ and $\omega_f$ are the initial and final angular speed of the wheel, and t the time.

In our problem, the initial angular speed is zero (the wheel starts from rest), so the angular acceleration is
$\alpha = \frac{(11.2 rad/s) - 0}{3.07 s} =3.65 rad/s^2$

(b) The wheel is moving by uniformly rotational accelerated motion, so the angle it covered after a time t is given by
$\theta (t) = \omega_i t + \frac{1}{2} \alpha t^2$
where $\omega_i = 0$ is the initial angular speed. So, the angle covered after a time t=3.07 s is
$\theta= \frac{1}{2} \alpha t^2 = \frac{1}{2}(3.65 rad/s^2)(3.07 s)^2 = 17.2 rad$
