Which change increases the extent (amount of product at equilibrium) for an exothermic forward reaction?
For the decomposition equilibrium 2 NO2 ? N2O4, which change would increase the amount of N2O4 at equilibrium?
Which experimental change increases the rate of reaction by increasing the frequency of successful collisions?
Which of these is a correct description of dynamic equilibrium?
Consider the reversible reaction A + B ? C + D. Removing some D from the mixture at equilibrium will cause:
Which of the following best defines a catalyst?
When the temperature is increased for the equilibrium 2HI ? H2 + I2, the equilibrium shifts to the right. What does this tell you about the forward reaction?
A reversible reaction releases 120 kJ when 2 moles of product form. If 1 mole reacts in the reverse direction, how much energy change occurs?
Which experimental change will increase the rate but NOT change the position of equilibrium for a reversible reaction?
Which factor will increase the rate of a gas-producing reaction between a metal and acid when all others are constant?
In a rate experiment, a student measures how long it takes to collect a fixed volume of gas. If the time measured increases, what does this indicate about the rate?
