    A question I just did asked to identify when the rate of water draining from a tank was draining at the fastest rate. I solved the second derivative and got a constant. The solution said that as the rate of drainage is a constant, check start and end point. From that, a new answer was deduced...

    ***galvanic cell issue***

    I'm currently having a serious issue with (re)learning galvanic cells. From the activity series, we know that a more active metal will displace a less active metal in solution, turning from an element into an ion + free electrons. We know that the less active element (currently in solution as...

    Why is K only affected by temperature?

    If you changed pressure/volume, wouldn't equilibrium lie to either side and hence different amounts of product and reactant are made, changing the value of K (as K = [P]/[R]) Likewise, if you change concentration of either P or R wouldn't that directly change K? The syllabus dot point is...
