Question

For reaction 2a + b products, the active, mass of b is kept constant and that of a is doubled. The rate of reaction will then

Answer 1

Hey dear,

● Answer -
Rate of reaction is quadrupled.

● Explanation -
Initially rate of the reaction is given by -
R = k.[2a]^2.[b]
R = 4k.[a]^2.[b]

When active mass of a is doubled, reaction rate is -
R' = 4k.[a']^2.[b]
R' = 4k.[2a]^2.[b]
R' = 16k.[a]^2.[b]
R' = 4R

Therefore, rate of reaction is increased 4 times.

Thanks for asking...
