A system at equilibrium is exothermic forward. Which of these will increase the product yield most dramatically?
Which set of conditions would be best to increase the yield of a product when the forward reaction is exothermic and produces fewer gas molecules than the reactants?
Consider the reaction N2(g) + 3H2(g) ? 2NH3(g), which is exothermic forward. Increasing temperature in the Haber process will:
Which practical change in an industrial exothermic equilibrium reactor would increase product yield without changing temperature?
For the heterogeneous equilibrium CaCO3(s) ? CaO(s) + CO2(g), increasing temperature will:
Which of the following statements about the effect of temperature on an equilibrium constant K is correct?
For the equilibrium A ? B, a decrease in temperature causes the position to move to the left. The forward reaction is therefore:
Which graph best shows the effect of a catalyst on a reaction energy profile (activation energy Ea and overall ?H unchanged)?
A system at equilibrium is exothermic in the forward direction. Which change would increase the equilibrium yield of products?
When a reaction is exothermic in the forward direction, which of these changes will increase K (equilibrium constant) for the forward reaction?
An endothermic forward reaction has activation energy Ea,f and reverse Ea,r. Adding heat (raising temperature) generally:
