For #1, the equation tells you 4 electrons are transferred and 1 electron transferred for #2. To balance the two half reactions for a complete reaction, you will multiply half reaction 1 by 1 and half reaction 2 by 4, then add the two half reactions/equations. That will give ...

Sure. You aren't substituting a negative number. You can't do that. You are calculating a value of log (0.197/0.803) and adding that to the pKa of the benzoic acid. The log term will be positive in some situations and negative in others. That is a mathematical operation. [By ...
