Answer 1

Answer:

For what values of k are the points (8,1) , (3,-2k) and (k,-5) collinear ?In this reaction the decomposition of potassium chlorate takes place. Since it is taking place in the presence of heat so it is thermal decomposition. Potassium chloride and oxygen gas are formed as a product. - So, this is thermal decomposition reactionLet A(x1=8,y1=1),B(x2=3,y2=−2k) & C(x3=k,y3=−5)

be the given point

The given points are collinear if

x1(y2−y3)+x2(y3−y1)+x3(y1−y2)=0

on puting values we get

8(−2k+5)+3(−5−1)+k(1+2k)=0

−16k+40−18+k+2k2=0

2x2−15x+22=0

2k2−4k−11k+22=0

2k(k−2)−11(k−2)=0

(2k−11)(k−2)=0

k=2
