Answer : The energy diagram is shown below.

Explanation :

Activated complex : When the reactant molecules absorb energy then their bonds are loosened and new lose bonds are formed between them.

The intermediate formed is known as activated complex and it is an unstable state and immediately dissociates to form the stable products.

Activation energy : It is defined as the minimum amount of energy absorbed by the reactant molecules so that their energy becomes equal to the threshold energy. Or we can say that, the difference between the reactant and the activated complex.

Enthalpy of reaction : It is defined as the energy change that takes place when the reactants go to the products. It is represented as, \Delta H. Or we can say that, the difference between the product energy and the reactant energy.

Hence, the energy diagram is shown below.

How much heat would be evolved (released) if 50.0g of steam is at 114°C was cooled and condensed into water at 87°C?
LuckyWell [14K]

Answer:

Q ≈ 1 x 10⁵ joules (1 sig. fig. based on 50g sample given)

Explanation:

Three heat transitions need be considered. Cooling the steam to 100°C, condensing the steam to water and cooling the water from 100°C to 87°C.

Total Heat exchange (Q) = ∑ heat transitions

Q = (m·c·ΔT)steam + (m·ΔH)condensation + (m·c·ΔT)water cooling

= (50g x 0.48j/g·°C x 14°C) + (50g x 2259j/g) + (50g x 4.184j/g·°C)

= 24j + 112,950j + 209.2j

= 113,183.2j ≈ 1 x 10⁵ joules (1 sig. fig. based on 50g sample given)
