The forward rate constant is the reverse rate constant is the reverse rate const

Question

The forward rate constant is the reverse rate constant is the reverse rate constant. The amount of B at equilibrium as the temperature increases. The forward reaction is probably. Compare the reaction energy diagrams for the three gas phase reactions shown below Assume that steric factors are all comparable and that entropy is not important in the following. Specify a reaction with its number (1, 2, or 3). The reaction with the largest rate constant is The reaction with largest equilibrium constant is The reaction whose equilibrium constant increases the most with an increase in temperature is The strongest bond is the bond. The weakest bond is the bond. Consider the following equilibrium: A+ B right harpoon over left harpoon C+D+ E delta H^0 > 0 Use Lechatelier's principle to predict the effect on the concentration of the equilibrium concentration of E caused by each of the following actions: adding A increasing the temperature

Explanation / Answer

The reaction with largest rate constant is: 2, as activation energy is high, according to arrhenius equation, the rate constant will be higher for the reaction 2.

The reaction with largest equlibrium constant is: 3, as equlibrium constant will be the ratio of concentrations of products divided by reactants, so in reaction 3 we get more products, as the product is very much stable as compared to reactant.

The reaction whose equlibrium constant increases the most with an increasae in temperature is: A, the change will be more visible in A, as it is seen that the reactants and product is having nearly equal energy, but by raising temperature, the Ea of the reaction is lowered and a significant change will be seen in A

The strongest bond is the A-D, as the product formed in this case is the most stable

The weakest bond is the A-C, as the product is less stable than the reactant in this case.

By adding A: The equilibrium concentration of E increases

By removing D, the equilibrium concentration of E increases

By increasing temperature, the equilibrium concentration of E increases
