In the given chemical equation 2HI ⇌ H2 + I2, with ΔH > 0, the forward reaction is endothermic, meaning it absorbs heat.
The forward reaction is affected by changes in temperature (B). Increasing the temperature would favor the endothermic direction to absorb more heat, shifting the equilibrium towards the products (H2 + I2) and promoting the forward reaction. Decreasing the temperature would shift the equilibrium towards the reactants (2HI) to compensate for the loss of heat.
So, the correct answer is B) Temperature.
