Answer:

True

Explanation:

In a chemical reaction, if the reactants have more potential energy than the products have, the extra energy is released to the surroundings as heat. This type of reaction is exothermic.

The activation energy is the difference between the energy of the reactants and the maximum energy (the activated complex).

The activated complex is the complex that exists as the bonds in the products are forming and the bonds in the reactants are breaking. This Complex exists when the energy of the system is at its maximum.

Answer:

The correct option is;

1. True

Explanation:

Here, we note that an activated complex is the intermediate form of the reactants during the conversion of the reactants into a product with a structure representing the point with maximum energy along the path of the reaction. As such here the complex forms a product the released energy will be more than the activation energy resulting in the exothermic reaction.

Two groups of students made plans to help their community during a hurricane. The first group suggested training the community a
zysi [14]
The correct option is D.
During hurricane, the most important thing is to get people out to safety in order to save their lives. Training the community about safety evacuation route is by far the better idea because it provide immediate safety from the natural hazard. The second idea is not a good one at all, because if food are stocked in every house in the community, the food will be destroyed alongside other things during the hurricane.

A power plant taps steam superheated by geothermal energy to 475 K (the temperature of the hot reservoir) and uses the steam to
jasenka [17]

Answer:

Thermal Efficiency, η = \frac{W₀}{Q₁}   . . . . . . . . . . . . . . . . Eqn 1

where W₀ = Work Output = Q₁ - Q₀ =82500KW    . . . . . . .    . . . . . . . . Eqn 2

Q₁ = Heat Supplied/Input = mC(ΔT₁)

Q₁ = Heat Rejected/Output = mC(ΔT₀)     . . . . . . . . . . . . . . . . . . . . . . . . Eqn 3

Note:  From Carnot's theorem, for any engine working between these two temperatures (T₀/T₁), The maximum attainable efficiency is the Carnot efficiency given as follows;

Therefore, η = 1 - \frac{Q₀}{Q₁} = 1 - \frac{T₀}{T₁}

Remember, T₁ = 475K and T₀ = 308K

η = 1 - (308/475) = 1 - 0.648 = 0.352

Hence, the maximum efficiency at which this plant can operate = 35%

2. To determine the minimum amount of rejected heat that must be removed from the condenser every twenty-four hours.

Remember from Eqn 1, Q₁ = W/η,

Therefore, Q₁=  82500/0.35

  Q₁=235,714KW,

So, from Eqn 2, Q₀ = 235714 - 82500

                                Q₀ = 153214KW (KJ/s)  (Released Heat)

In t =24 hours, we can then use this to determine the minimum amount of heat rejected qₓ (KiloJoule),  = Q₀t  (Remember, you have to convert the time, t, unit to seconds)

                                           = 153214 x t (KiloJoule)

qₓ = 153214 x 24 x 3600 (KiloJoule)

qₓ = 13238 MegaJoule

<h3>Therefore, the minimum amount of rejected heat that must be removed from the condenser every twenty-four hours is 13238 MJoule</h3>
