t takes 0.4 minutes for an enzyme-controlled reaction to occur.Calculate the rate of reaction per minute.(How many reactions will occur in a minute? Do not include units in your answer.)Give your answer to 1 decimal place.

A biochemical reaction was carried out in the absence of enzyme and the rate of reaction was found to be 10^6 min-1. If the same reaction is now carried out in presence of enzyme, then the rate of the reaction will be and what is the activation energy for the same reaction in presence of enzyme1. same2.greater than 10^63.less than 10^6

A first-order reaction has a half-life of 20 seconds. Calculate the rate constant for this reaction. GIve your answer to 3 decimal places.

The rate constant of a first order reaction is 4×10−3sec−1 .At a reactant concentration of 0.02 M, the rate of reaction would be:

Time required for completion of 99.9% of a First order reaction is ________ times of half life (t1/2) of the reaction.

What is the rate of Enzyme reaction and what are the factors that affect it.
