Homework Statement
Why is it harder to start a battery in winter rather then summer?
Homework Equations
Nerst Equation
Ecell = Ecell - RT/zf(lnQ)
The Attempt at a Solution
Isn't the lead sulfate bettery unique such that the electroyte for the anode and cathode is the same Pb(SO4). Shouldn't that mean that Q should always be 1 therefore ln(1) is 0. This would mean temperature has no affect on voltage. I'm confused though because I know cars are harder to start during the winter.
