The rate constant for a particular the concentration to decrease to

The following series of diagrams represent the reaction XY followed over a period of time. The X molecules are red and the Y molecules are green. At the end of the time period depicted, has the reaction system reached equilibrium? Justify your answer with a one-sentence explanation.

When molecules collide, a certain minimum energy called the _________ is needed for the reaction to occur.

Old-fashioned smelling salts consist of ammonium carbonate, (NH4)2CO3. The reaction for the decomposition of ammonium carbonate (NH4)2CO3(s)2NH3(g)+CO(g)+H2O(g) is endothermic. Would the smell of ammonia increase or decrease as the temperature is increased?

Consider the following hypothetical reaction: A+BC Calculate the average rate of the reaction on the basis of the following information: a. Pure A and B are mixed, and after 12.0minutes the measured concentration of C is 0.396mol/L. b. Pure A,B, and C are mixed together at equal concentrations of 0.300M. After 8.00minutes, the concentration of C is found to be 0.455M.

The equilibrium constant expression for a given reaction depends on how the equilibrium equation is written. Explain the meaning of that statement. You may, if you wish, use the equilibrium equation N2(g)+3H2(g)2NH3(g) to illustrate your explanation.

A reaction is run at 10C and takes 3.7hours to go to completion. How long would it take to complete the reaction at 30C?

Consider the following hypothetical reaction: A+BC Calculate the average rate of the reaction on the basis of the following information: a. Pure A,B, and C are mixed together at concentrations of A+B=0.400M, C=0.150M. After 6.00minutes, the concentration of C is 0.418M. b. Pure A, and B are mixed together at same concentrations of 0.361M. After 7.00minutes, the concentration of A is found to be 0.048M.

For the endothermic reaction AB(g)A(g)+B(g), the following represents a reaction container at two different temperatures. Which one (I or II) is at the lower temperature?

. Equilibrium may be defined as the ________ of two processes, one of which is the opposite of the other.
