<span>At room temperature and atmospheric pressure, nothing happens when the two gasses are mixed. However, at high temperature and pressure (450C, 200atm), in the presence of an iron oxide catalyst, the production of ammonia is thermodynamically advantageous.</span>
Ka and Kb values of weak acids and weak bases are small.
This is because weak acids and weak bases do not dissociate completely, favoring the reactants more than dissociating into the product of H+ or OH-.
Answer:
a.Low temperature
Explanation
Equation of reaction:
2NO2 <==> N2O4(g) ∆H = +ve
To cause the reaction to become darker brown means to produce more of NO2 gas. That is backward reaction.
Since the reaction is endothermic, decrease in temperature will shift the equilibrium position to the left thereby favouring backward reaction. This is in line with Me Chatelier's principle.
High pressure will rather favour forward reaction (it is not the right option).
Answer:
