NEET 2024 Re Exam Physics and Chemistry Paper

N2(g)+3H2(g)⇌2NH3(g),∆H=−Q
According to Le Chatelier's principle.
• Exothermic reactions are favoured at low temperature.
• Increase in pressure shifts the reaction in direction having lesser number of moles. Hence, the given reaction shifts forward on increasing pressure.
• Increasing the concentration of reactants shifts the reaction in forward direction. So high concentration of H2 shifts reaction in forward direction.
