- When writing an equation, how is a reversible reaction distinguished from a nonreversible reaction?arrow_forwardWhich of the following is true of reduction reaction? It is the removal of electrons from an atom or molecule. They are also referred to as dehydrogenation reactions An example of which is the conversion of Pyruvic acid to Lactic acid There is a decrease in the potential energy of the atom or molecule Which cells in the body convert most of the remaining fructose and practically all of the galactose to glucose? Sertoli cells Erythrocytes Parietal cells Hepatocytes Which of the following substances can be considered as metabolic intermediates?* Water ATP Pyruvic acid Glucosearrow_forwardWhich of the following will increase the production of Oz in the following reversible reaction?arrow_forward
- (a) Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion.Reaction rates increase with increasing temperature.The slowest step in a reaction is called the rate-determining step.Catalysts increase reaction rates.The fastest step in a reaction is called the rate-determining step.As a reaction progresses its rate goes down.Reaction rates can show little change as masses of solid reactants increase.arrow_forwardConsider the reversible reaction shown below. What effect, if any, would each of the following stresses have on the position of equilibrium? CO(NH2)2 (l) + 2 HCl (g) ↔ 2 NH3 (g) + COCl2 (g) ; ∆H = -10.0 kJ/mol Addition of a suitable catalyst Addition of gaseous ammonia An increase in temperature Removing gaseous ammonia The system is compressed (increase total pressure) hints: give answers as directions or the favored side of the reactionarrow_forwardWhich would you predict to react at a faster rate when all other conditions are equal? Br2 gas Br2 liquidarrow_forward
- 2) The equilibrium constant Ke for the reaction A B is 1 x 105 at room temperature (25°C). a) You make a solution containing compound A at a concentration of 1 M and compound B at a concentration of 1 mM of B, and let the reaction proceed to equilibrium. What are the equilibrium concentrations of A and B? b) Calculate the standard free-energy change (AG) for this reaction. c) What is the standard free-energy change (AG) for the inverse reaction (BA)?arrow_forwardA thermodynamically-controlled process describes a reaction that, generates the most stable product O generates the product whose formation requires the smallest energy of activation O generates the product requiring the fewest steps O generates the product formed at the fastest rate O generates the product favored at low temperaturesarrow_forwardGiven this reaction at equilibrium, C(s) + CO2(g) D 2CO(g) (∆H° = 119kJ), explain the changes that would occur when the following stresses are applied or removed for this reaction. CO is removed. Heat is added. CO2 is added. Heat is removed.arrow_forward
