Ammonia, NH3, can be made by reacting nitrogen and the equation is N2 + 3H2 --&gt; 2NH3 How many moles of NH3 can be made if 18
alukav5142 [94]
N2 + 3 H2 -> 2 NH3 
<span>Just use their stoichiometric coefficients (number before the chemical's name) from the balanced chemical reaction to make ratios and solve for the unknown. In this case, 2 moles of NH3 are produced for every 3 moles of H2. Thus, </span>
<span>7.5 moles H2 x (2 moles NH3 / 3 moles H2) = 5 moles NH3

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!
