`A + B rarr` Product, `(d x)/(d t) = k[A]^(a)[B]^(b)`
If `((d x)/(d t)) = k`, then order is:

If the differential equation of a damped oscillator is (m d^(2)x)/(d t^(2)) + (bd x)/(d t) + k x = 0 then energy of damped oscillator vary with time .t. is E(t) =

For a reaction of the type Aa+bB rarr products ( -)(d[A])/(dt) is equal to (A) (-d[B])/(dt) (B) -(b)/(d)(d[B])/(dt) (C) -(a)/(b)times(d[B])/(dt) (D) -(b)/(a)times(d[B])/(dt)

The rate of reaction is expressed as : (1)/(2)(+d)/(d t)[C] = (1)/(3)(-d)/(d t)[D] = (1)/(4)(+d)/(d t)[A] = -(d)/(d t)[B] The reaction is:

For a reation: A rarr Product, rate law is -(d[A])/(dt)=K[A]_(0) . The concentration of A left after time t when t=1/K is:
