Consider the reaction below. A + 3B → 2C + 2D

The rate increases by a factor of 9 when the concentration of A triples. The rate triples when the concentration of B triples. What is the new rate law for the reaction?

A. R=K[A] [B]

B. R=K[A] [B]

C. R=K[A] [B]

D. R=K[A]° B]​

The answer to this problem is. 67

Sorry i think the answer is b

The answer to this question is a

Electron equations of the given changes are as follow,a)                              cu      →      cu⁺²  + 2e⁻b)                              mg⁺²  +  2 e⁻      →      mgc)                              cl⁻    →      cl  +  1e⁻d)                              s  +  2 e⁻    →      s²⁻e)                                o²⁻      →      o  +  2 e⁻f)                              p  +  3 e⁻    →      p³⁻g)                              fe²⁺    →      fe³⁺  + 1 e⁻h)                              s²⁻    →      s⁴⁺  +  6 e⁻
