find something that can help me solve the answer for An endothermic reaction has an activation energy of 95 kJ in the forward direction and an activation energy of 55 kJ in the reverse direction. Sketch the potential energy diagram and label the EA(Forward) , EA(Reverse) and determine and label the △HReverse. (5 marks)

Which of the following describes an exothermic reaction?A.Hf, reactants = 0B.Hf, reactants = Hf, productsC.Hf, reactants > Hf, productsD.Hf, reactants < Hf, products

What is the activation energy of a reaction?A.The speed at which the molecules must be moving in order to reactB.The kinetic energy of the colliding moleculesC.The energy that is given off when a reaction happensD.The energy the molecules must have in order to reactSUBMITarrow_backPREVIOUS

A minimum amount of energy is required to start a chemical reaction. What is this energy called?Activation energyEndothermic energyReaction energyExothermic energy2On a reaction profile, what does the difference between the reactants line and the products line represent?The energy changeThe activation energyThe temperature changeThe amount of product formed3If the energy change on a reaction profile goes down, what does this tell you about the reaction?It is exothermicMore heat is requiredThere is not enough reactantIt is endothermic4Which of the following statements about endothermic reactions is true?They do not require any activation energyThe products will always have less energy than the reactantsThe products will always have more energy than the reactantsThe products will always have the same energy as the reactants

Give the general equation for an exothermic reaction. a reactants → products + energy b products → reactants - energy c products → reactants + energy d reactants → products - energy
