D. Yep, D is the answer, alright.
B is the answer. For an equation to be balanced there must be the same amount of each element on the two sides. The only one where this is the case is B.
A catalyst reduces H°rnx in most reactions. The answer is false
<h3>Do catalysts reduce delta H?</h3>
By reducing the activation energy required for the reaction to occur, a catalyst just modifies the route used to go from reactants to products. However, because it doesn't alter the state of the products or reactants, delta H is unaffected.
A catalyst reduces a reaction's activation energy, enabling a chemical reaction to occur. The number of reactant particles with energy above the activation energy increases as the temperature of a reaction rises.
