Which of the following statements about the protein enzymes (catalyst) is NOT true Within living organisms,most protein enzymes are regulated. The activity of enzymes (e.g alcohol dehydrogenase) can be affected by substances such as inhibitors. Some protein enzymes catalyze reactions at rates that are typically 10^6 to 10^12 times faser than uncatalyzed reactions. Almost all protein enzymes from living system can catalyse reactions under harsh conditions. such as temperatures above 100 degree C and at extremes of pH. Protein enzymes bind to substrates with both structural and chemical complemontanly. None of the above. For the following reaction Delta H = 180.5kj. Which of the following would shift the equilibrium toward the reactants in the following reaction N_2(g) + O_2(g) reversible NO(g Adding diatomic nitrogen Removing NO Adding a catalyst Decreasing the pressure Increasing the temperatureWhich chemical acts as a catalyst in the overall depletion of ozone (O_2) O_3 + Cl reversible O-2 + ClO O_3 + ClO reversible 2O_2 +Cl Cl ClO O_2 O_3 Fe^3+ A solution that contains a 3.594 * 10^-3 M concentration of hydroxide ion would be classified as: Slightly Basic Slightly Acidic Neutral Very Soluble BoilingExplanation / Answer
I am allowed to answer only 1 question at a time
I don't know question 6. So I am answering question 7
I will explain it thoroughly
7)
A)
adding reactant shift the reaction towards product
N2 is reactant . SO adding N2 will shift the reaction towards product
False
B)
Removing NO (product) will shift reaction towards product
False
C)
Adding a catalyst has no effect on equilibrium. It just makes the equilibrium reach faster
False
D)
Decreasing pressure will shift reaction to the side where there is more gaseous molecules
So it will shift reaction towards reactant
True
Answer: D
