Question: In a chemical equilibrium, the rate constant of the backward reaction is \(7.5 \times 10 ^ { - 4 }\)...

In a chemical equilibrium, the rate constant of the backward reaction is 7.5×10−47.5 \times 10 ^ { - 4 } and the equilibrium constant is 1.5. So the rate constant of the forward reaction is.

A

5×10−45 \times 10 ^ { - 4 }

B

2×10−32 \times 10 ^ { - 3 }

C

1.125×10−31.125 \times 10 ^ { - 3 }

D

9.0×10−49.0 \times 10 ^ { - 4 }

Answer

1.125×10−31.125 \times 10 ^ { - 3 }

Explanation

Solution

=1.125×10−3= 1.125 \times 10 ^ { - 3 }
