1.
A catalyst increases rate by:
increasing particle energy
providing a route with lower Ea
shifting equilibrium right
increasing ΔH
2.
At higher temperature the Maxwell-Boltzmann peak:
moves right and is lower
moves left and is higher
stays the same
moves right and is higher
3.
Increasing pressure for N2 + 3H2 ⇌ 2NH3 shifts equilibrium:
left
not at all
right
to form more N2
4.
Which statement about dynamic equilibrium is true?
Reactions have stopped
Concentrations are equal
It occurs in an open system
Forward and reverse rates are equal
5.
Why is ~450 °C used in the Haber process?
It gives the highest yield
It is a compromise between rate and yield
The catalyst melts below it
The reaction is endothermic
6.
Area under a Maxwell-Boltzmann curve represents:
activation energy
average energy
total number of molecules
rate constant
7.
Which statement best describes Rate of reaction?
A graph showing how the kinetic energies of gas molecules are spread at a given temperature.
The change in concentration of a reactant or product per unit time, in mol dm-3 s-1.
A catalyst in a different phase from the reactants, e.g. iron in the Haber process.
A substance that increases the rate of a reaction by providing an alternative pathway of lower activation energy, and is unchanged at the end.
8.
Which statement best describes Collision theory?
Reactions occur only when particles collide with the correct orientation and at least the activation energy.
The minimum energy colliding particles need for a reaction to occur.
The change in concentration of a reactant or product per unit time, in mol dm-3 s-1.
If a system at equilibrium is disturbed, the position of equilibrium shifts to oppose the change.
9.
Which statement best describes Maxwell-Boltzmann distribution?
A catalyst in the same phase as the reactants.
The minimum energy colliding particles need for a reaction to occur.
A graph showing how the kinetic energies of gas molecules are spread at a given temperature.
Reactions occur only when particles collide with the correct orientation and at least the activation energy.
10.
Which statement best describes Activation energy?
A catalyst in a different phase from the reactants, e.g. iron in the Haber process.
A catalyst in the same phase as the reactants.
The minimum energy colliding particles need for a reaction to occur.
The change in concentration of a reactant or product per unit time, in mol dm-3 s-1.
