For the reaction ,`A+ 2B to C ,` the rate of reaction at a given instant can be represented by __________.

Options

A. `+(d[A])/(dt)=+1/2(d[B])/(dt)=+(d[C])/(dt)`
B. `+(d[A])/(dt)=+1/2(d[B])/(dt)=-(d[C])/(dt)`
C. `-(d[A])/(dt)=-1/2(d[B])/(dt)=+(d[C])/(dt)`
D. `+1/2(d[A])/(dt)=+1/2(d[B])/(dt)=+(d[C])/(dt)`

Explanation

In the reaction ` A + 2 B to C `, the reactant A and B are consumed and product C is formed . The instantaneous rate of the reaction can be represented as :
`- (d[A])/(dt) = - (1)/(2) (d[B])/(dt) = + (d[C])/(dt)`
