1.

For the reaction A + 2B to 2C + D, the concentration of A is kept constant and that of B is tripled, the rate of reaction will become

Answer»

three times
SIX times
eight times
nine times

Solution :INITIAL `"RATE"_1= k [A]^x[B]^(2Y)`
New `"rate"_2=k[A]^x[3B]^(2y)`
`:. ("rate"_2)/("rate"_1)= 3^2=9:."rate"_2 = 9 XX "rate"_1`
