Indicate how the concentration of each species in the chemical equation will change to reestablish equilibrium after reactant or product is added. Click in each box to toggle in the relative change in concentration (up = increases, down = decreases, leave the box blank for no charge). 2CO(g) + O_2(g) rlhar 2CO_2(g) a) after increasing the concentration of CO b) after increasing the concentration of CO_2

If the equilibrium concentration of each product is [0.035 M], and the equilibrium concentration of [HNO2] is 0.15, what is the equilibrium constant (K)? (please do not input answer using scientific notation). Based on the information given in the previous question, what is the pH of the solution?
4. (4 points) The free energy change of the reaction A(g) → B (g) is zero under certain conditions. The standard free energy change of the reaction is -42.53. Circle ANY of the following that must be true about the reaction. a) The concentration of the product is greater than the concentration of the reactant. b) The reaction is at equilibrium. c) The concentration of the reactant is greater than the concentration of the product.
True or false? & What is the product?
The elution order does not change when the solvent is changed to a more polar solvent. True False Chose the expected organic product for the benzoic condensation shown below.
Question 15 You have an unknown concentration of reactant A to form products B in a closed system (see the following equilibrium). Initially there is no product B at the beginning of the reaction. A (aq) — B(aq) K = 1.0 If the equilibrium constant is doubled (K = 2.0), how will the percentage yield of product B change at equilibrium state? The yield will increase by 33%. More information is needed for this question The yield will increase a...
The rate of the reaction in terms of the "disappearance of reactant" includes the change in the concentration of the reactant, the time interval, and the coefficient of the reactant. Consider the following reaction: 2A+3B→3C+2D The concentrations of reactant A at three different time intervals are given. Use the following data to determine the average rate of reaction in terms of the disappearance of reactant A between time = 0 s and time = 20 s. Time (s) 0 20 40...
2A + 3B ----> 3D Assuming that doubling the concentration of reactant A causes no change in rate and doubling the concentration of reactant B causes the rate to double, what is the rate law? a. Rate = k[B]2 b. Rate = k[A]2[B] c. Rate = k[A][B]2 d. Rate = k[B] e. Rate = k[A]
