Bond-breaking can be described as an exothermic process

• True

• False

During an exothermic reaction, energy...

• is converted to products

• is absorbed by reactants

• stays the same

• released into the surroundings

A negative ΔH is indicative of an

A catalyst is used to

• Increase the concentration of reactants

• Decrease the activation energy of the reaction

• Increase the activation energy of the reaction

• Decrease the speed of the reaction

The energy of product(s) is greater than the energy of reactant(s) for an endothermic reaction

• True

• False

Define 'Heat of Neutralization'

State 2 assumptions made during enthalpy calculations

Photosynthesis is an example of an

The enthalpy change of a reaction is -57kJ/mol. Is the reaction endothermic or exothermic?

• Endothermic

• Exothermic

The reaction between an acid and a base is called

• A decomposition reaction

• Displacement reaction

• A neutralization reaction

• Combustion reaction
