Question:

Rate law for the reaction is giving below. The reaction rate is multiplied by _____ if the concentration of B and C is doubled.

Rate = {eq}[ A ]^2 [ B ] [ C ]^o {/eq}

a) 4

b) 6

c) 2

d) No change in the reaction rate.

Rate Law:

{eq}\\ {/eq}

The rate law is an equation that describes the mathematical relationship between the rate of a chemical reaction and the concentration of reaction, as well as product in some cases.

The general equation of rate law is of the form:

{eq}\rm Rate=[A]^x[B]^y[C]^z.. {/eq}

Here,

  • {eq}\rm [A],\; [B]\;and\;[C] {/eq} denotes the molar concentration of {eq}\rm A, \; B,\;and\; C {/eq} respectively.
  • {eq}\rm x,\;y ,\;z {/eq} are dimensionless numbers.
  • {eq}k {/eq} is called the rate constant. Its value is determined experimentally.

{eq}\\ {/eq}

We are given:

  • The reaction rate, {eq}\rm Rate=[A]^2[B][C]^0 {/eq}


Since the exponential of {eq}\rm [C] {/eq} is {eq}0 {/eq}, its...
