Question

A)

What is the energy of the reactants?

b) What is the energy of the products?

c) Calculate ΔH.
How would you classify the reaction based on its energy change? Explain.

d) Calculate the activation energy for this reaction.

e) How much energy is released during the formation of the products?

f ) Explain why you have goose bumps when coming out of the pool on a hot sunny day.

Answer 1

Step-by-step explanation:

a )

From the graph given , energy of reactant = 0

b )

energy of product = -15 kJ

c )

ΔH = energy of product - energy of reactant

= -15 - 0 = - 15 kJ

ΔH is negative so reaction is exothermic .

d ) Activation energy = 25 - 0 = 25 kJ .

e ) Energy released = 15 kJ .
