Question

For a chemical reaction ` A to B` it is found that the rate of reaction doubles , when the concentration of A is increased four times . The order in A for this reaction is
A. Two
B. One
C. Half
D. Zero

Answer 1

Correct Answer - c
`r = k[A]^(m)` also 2r = `k[4A]^(m) , (1)/(2) = ((1)/(4))^(m)`
`therefore m = (1)/(2).`
