Draw the PE diagram (use specific numbers) showing the PE changes that occur during a successful collision of the reaction: H2+Br22HBr+105KJ The PE of the reactants =180KJ The activation energy of the forward reaction =90KJ a) What is the activation energy of the reverse reaction? b) What is the PE of the products? Label: PE of reactants, products, activated complex, and activation energy of forward and reverse reactions. Write a dissociation equation to represent the equilibrium of saturated solution of germanium phosphate. Write the solubility product (Ksp expression) for the of the equilibrium system
