2 X(9) + Y (9) = 2XY (9) A reversible reaction is represented by the equation above. The amounts of reactants and products at time 1 are shown in the particle diagram on the left. The particle diagram on the right shows the
amounts of reactants and products at time 2. Based on the diagrams, what can be inferred about the relative rates of the forward and reverse reactions between time 1 and time 2?
a. nothing can be inferred because the total number of X and Y atoms is the same
each diagram

b. Nothing can be inferred because the temperature of the system may have been changed
c. The rate of the reverse reaction is greater than the rate of the forward reaction
d. The rate of the forward reaction is greater than the rate of the reverse reaction.
