Question 7: An experiment carried out to study the effect of the mole contents of cobalt (1) and the calcination temperature (2) on the surface area of an iron cobalt hydroxide catalyst (y)

resulted in the accompanying data.

1 0.6 0.6 0.6 1.0 1.0 2.6 2.6

2 200 250 400 500 600 250 500

y 90.6 82.7 58.7 17.8 9.1 52.0 42.4

Predict the value of surface area when cobalt content is 2.6 and temperature is 250. Also find​
