The gas in a closed container has a pressure of 3.00 x 10² kPa 30 ° C. What will the pressure be if the temperature is lowered t
Rainbow [258]

Answer: 100kPa

Explanation:

P1 = 3.00 x 10² kPa , P2 =?

T1 = 30°C = 30 +273 = 303k

T2 = —172°C = —172 + 273 = 101k

P1/T1 = P2/T2

3 x 10² / 303 = P2 / 101

P2 = (3 x 10² / 303) x 101

P2 = 100kPa

What letter represents the activation energy for the reverse reaction?
Bezzdna [24]

<u>Answer:</u> The correct answer is Option 4: U

<u>Explanation:</u>

Activation energy is defined as the energy that is given to a chemical system with potential reactants to produce products. It is represented as E_{ac}

It is represented as the energy from the reactants to the activated complex.

Reverse reaction is defined as the reaction in which the products formed become reactants and leads to the formation of reactants back.

So, here, the activation energy of the reverse reaction is the energy between the products and the activated complex, which is represented as letter U in the given graph.

Hence, the correct answer is Option 4: U
