A certain reaction has an enthalpy of Δ=44 kJ and an activation energy of a=61 kJ. What is the activation energy of the reverse
avanturin [10]

Answer:

E = 17 kJ

Explanation:

The enthalpy of the reaction is:

\Delta H = E_{p} - E_{r}  

<u>Where</u>:

Ep: is the energy of the products

Er: is the energy of the reactants

Similarly, the enthalpy of the reaction is related to the activation energy forward (E_{F}) and to the activation energy reverse (E_{R}) as follows:

\Delta H = E_{F} - E_{R}  

Having that ΔH = 44 kJ and E_{F} = 61 kJ, the activation energy of the reverse reaction is:

E_{R} = E_{F} - \Delta H = 61 kJ - 44 kJ = 17 kJ  

Therefore, the activation energy of the reverse reaction is 17 kJ.

I hope it helps you!

Cuantos gramos de nitrato de potasio (KNO3) son necesarias para preparar 800ml de solucion al 12 % m/v
maxonik [38]

Answer:

96 g

Explanation:

Tomando en cuenta que estamos hablando de una solución de Nitrato de potasio cuya concentración es 12% m/V, debemos entonces usar la expresión de %m/V:

%m/V = msto / Vsol * 100   (1)

De esta expresión, debemos despejar la masa de soluto (msto) que es precisamente el valor que estamos buscando. Al hacer el despeje tenemos:

msto = %m/V * Vsol / 100    (2)

Ahora solo nos queda sustituir los valores dados y resolver:

msto = 12 * 800 / 100

<h2>msto = 96 g de KNO₃</h2>

Espero te sirva.
