In the reaction 2 NO(g) + O2(g) ? 2 NO2(g) the forward reaction is exothermic. What is the effect on equilibrium yield of NO2 if temperature is decreased?
A reaction is observed to have a linear increase in rate when [A] is doubled, but a quadratic increase when [B] is doubled. What is the overall order of the reaction?
In the reversible reaction A + B ? C + D at equilibrium, what is the effect of adding more B?
A student measures initial rate for A ? products at three concentrations: [A] = 0.10 ? rate 0.020; [A] = 0.20 ? rate 0.040. What is the order with respect to A?
Which experimental observation shows that increasing concentration affects the extent (equilibrium) rather than just the rate?
Which effect on an equilibrium is produced by removing some product as it forms (for a reaction aA ? bB)?
A weak acid and a strong acid have the same concentration. Which statement about their pH is correct?
Which combination will increase the yield of products for the reaction 2 A(g) ? B(g) (endothermic forward)?
Which of the following is an EFFECT of increasing concentration of reactants in a gas-phase equilibrium (at constant temperature) for an exothermic forward reaction where total gas moles decrease?
During a titration the concentration of the titrant is halved. To obtain the same number of moles of titrant reacted you must:
Which statement about concentration and rate of reaction is FALSE?
