Analyse data and interpret graphical representations of relative changes in the concentration of reactants and product against time, to determine the position of equilibrium. Factors that affect equilibrium

A reversible reaction \(\text{P}(g) + 2\text{Q}(g) \rightleftharpoons \text{R}(g)\) reaches equilibrium. The graph shows the concentration changes of P, Q and R over time. At equilibrium (after 40 s), [P] = 1.0 mol L⁻¹, [Q] = 0.8 mol L⁻¹, and [R] = 1.0 mol L⁻¹. Determine whether the equilibrium position lies towards the products or reactants.

A reversible reaction \(2\text{A}(g) + \text{B}(g) \rightleftharpoons 2\text{C}(g)\) reaches equilibrium at time \(t_1\). Analyse the concentration-time graph to determine the correct statement about the position of equilibrium.

Determine if the relative position of equilibrium lies towards the products or reactants, if the molar concentrations at equilibrium are 0.80 mol L⁻¹ for SO₂, 0.60 mol L⁻¹ for O₂ and 1.2 mol L⁻¹ for SO₃. Explain your reasoning.
