Question
please show clear answer
Consider the gas phase reaction A+ 3B = 2C. To maximize the production of C, should you increase or decrease the overall pressure? Explain your answer. True or False? If we double all the coefficients in an electrochemical cell's overall reaction, charge number N is doubled but the cell's potential is unchanged. If the answer is false, explain why. If an acid is held at a fixed distance away from a positively charged surface, will it be stronger or weaker than in the absence of the charged surface? Explain your answer. True or false? When an electrochemical half reaction is multiplied by 2, its standard reduction potential is multiplied by 2. If the answer is false, explain why.Explanation / Answer
a) For the given reaction, to maximize the production of C, we should increase the overall pressure so the reaction equilibrium shifts to the direction to lowest moles of gas, that is towards product end.
b) True : If we double coefficients in an electrochemical cell, the charge doubles but potential remained same.
c) If acid is held at a certain distance from +vely charged surface, it will be stronger in the absence of the base as chances of it dissociating into H+ and counterion is higher.
d) False, the standard reduction potential is based on minimum coeeficient needed for half-reaction.
