The rate law for the reaction A + B product is rate =k[A][B] . When will the rate of reaction increase by factor two?
Options
- A[ A ] and [ B ] both are doubled
- B[A] is doubled and [B] is kept constant
- C[ B ] is doubled and [ A ] is halved
- D[ A ] is kept constant [ B ] is halved
Correct answer
B. [A] is doubled and [B] is kept constant
Step-by-step solution
aligned & Rate = k [ A ][ B ] & ( Rate )₁= k 2[ ~A ][ B ] & ( Rate )₁ Rate = k 2[ ~A ][ B ] k [ A ][ B ] =2 & ( Rate )₁=2 Rate aligned
