In a previous post, we were introduced to Pascal's Hexagrammum Mysticum Theorem - a magical theorem - which states that if we draw a hexagon inscribed in a conic section then the three pairs of opposite sides of the hexagon intersect at three points which lie on a straight line.

Which reaction has a minimum increase in the rate of reaction for a 10^@ increase in temperature?
• Backward Reaction
• Forward Reaction
###### Solution
We know:
k = Ae^(-E/(RT)) where E is energy of activation.
This can be written as ln k = ln A - (E/(RT))
lnk_2-lnk_1=E/R(1/T_1-1/(T_1+10))

Simplifying Ratios
Lesson
We like to express ratios as whole numbers, using the simplest numbers possible. We simplify ratios in a similar way to how we simplify fractions. To do this, we often divide by the highest common factor (HCF).

I think you might have misunderstood the heuristic function. It is supposed to give an underestimate on the distance from a node $n$ to the goal node $t$. The closer this estimate is to the true value, the better A* will perform.
