The equation below shows the equilibrium between $\text{N}_2\text{O}_4$ and $\text{NO}_2$ in a sealed container at a high temperature. $\text{N}_2\text{O}_4(g) \rightleftharpoons 2\text{NO}_2(g)$ Predict how the position of equilibrium changes when the pressure is reduced. Explain your answer. prediction explanation
The table gives the concentration of $\text{NO}_2$ in the sealed container at three different temperatures. State what this tells you about the enthalpy change for the forward reaction. Explain your answer. enthalpy change explanation
Nitrogen dioxide, $\text{NO}_2$, is produced when lead(II) nitrate, $\text{Pb(NO}_3)_2$, is heated. The remaining products are lead(II) oxide and a gas that relights a glowing splint. Write the equation for this reaction.
