The reaction of nitrogen(g) with hydrogen(g) to form ammonia(g) proceeds as follows: N2(g) 3H2(g)2NH3(g) When 6.44 grams of N2(g

) react with sufficient H2(g), 21.2 kJ of energy are evolved. What is the value of H for the chemical equation given

The enthalpy of the reaction is obtained as 4.876 kJ.

<h3>What is the enthalpy?</h3>

The enthalpy of a reaction is the heat that is absorbed or emitted in a reaction.

Given the reaction; N2(g) + 3H2(g) ⇔2NH3(g);

Number of moles of N2 = 6.44 grams/28 g/mol

= 0.23 moles

If 1 mole of N2 releases 21.2 kJ of energy

0.23 moles of N2 releases 0.23 moles *  21.2 kJ /1 mole

= 4.876 kJ

Alchen [17]
Because density=mass/volume, the density of a substance would increase if the mass was increased and the volume was not, and decreased if the volume was increased and the mass was not.

Hi guys, my question is:
guapka [62]

Answer:

See Explanation Below

Explanation:

A) The rate law can only be on the reactant side and you can only determine it after you get the net ionic equation because of spectators cancelling out. So in this case the rate law is k=[CH3Br]^1 [OH-]^1. The powers are there because the rxn is first order.  

B) Since the rxn is first order anything you do to it will be the exact same "counter rxn" per say so since you are decreasing the OH- by 5 the rate will decease by 5

C) The rate will increase by 4 since you are doubling both you have to multiply them both.
