We must remember that Nitrogen and Hydrogen are both diatomic molecules in their standard gas form. A fraction has two parts, namely. The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. Currently, we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of . of moles of ammonia formed when 3 moles of H 2 react with excess of N 2=2 The balanced equation will appear above. First, compare the total number of atoms of each element on the reactant side and the product side. It follows logically that also ammonia cannot decompose (as it would to a small extent in an equillibrium reaction), because otherwise it would decompose completely with time, although it is stable. Therefore, they have to carry out this reaction at high temperature with high pressure and catalytic solution. why we need to place adverts ? 3 H X 2 ( g) + N X 2 ( g) 2 N H X 3 ( g) forward reaction. This is anoxidation-reduction (redox) reaction. Most questions answered within 4 hours. Want to see the full answer?
