Question 35 (1 point) The relationship between the activation energy of the forward and reverse reactions is related by the energy difference between the reactants and products. If the reactants are higher in energy than the products, the activation energy for the forward reaction will be smaller than the activation energy for the reverse reaction and vice versa True False Question 36 (1 point) A catalyst is a substance that is not used up during a reaction. It also does...
If you wanted to double $1,000 in 10 years' time, what average rate of return would you require on your investment?
For the reaction coordinate diagram shown below, which of the following statements are true? Energy Reaction Coordinate True AErxn = A-C True Reaction is endothermic False Ea(forward) = Ea(reverse) True A represents the energy of the starting materials False Ea(forward) = B-C True Eg of the forward reaction is less than Ea of the reverse reaction Remember that thermodynamic quantities are calculated by products - reactants. The activation energy can be thought of as the barrier height.
ENERGY FROM CHEMICAL REACTIONS (page 8) Many chemical reactions release energy, while others require energy to happen. These energy changes that occur during chemical reactions are due to changes in bonding between the reactant molecules and product molecules. Breaking bonds between atoms always requires energy, while creating bonds between atoms always releases energy. Analyze each of the two chemical reactions below by calculating the total amount of energy needed to break the bonds in the reactants, the total amount of...
