as in one book it says 273k and elsewhere says 298k
also what is meant by standard rates

The standard condition for temperature is room temperature. This is anywhere between 20 Celsius and 25 Celsius (around 293 - 298 Kelvin) - This should be given to you in an exam, though.
The standard rate of a reaction is the time taken when all the reactants are in their standard states under standard conditions.

so standard rates are the time taken or are they the physical states under standard conditions and
In enthalpy change of formation can more than one product be formed

It is the time taken.

Also, no, enthalpy change of formation can surround the forming of more than one product.

so enthalpy change of formation is the energy change that occurs when 1 mole of a compound is formed but for there to be two compunds formed would both have to be one mole?
also i meant what are standard rates sorry

Yes, both would have to be one mole.

Yes, a standard rate is the time taken for a reaction to occur when the reactants are in their standard states and the reaction takes place in standard conditions.

The state of the compound in the standard conditions. e.g solid, liquid or gas.

In the enthalpy of formation? No.
