The equation G°_rxn = - RT LnK_p shows that there is a relationship between K_p and T.

This is expressed by the van't Hoff equation: Ln(K₂/K₁) = (H°/R)(1/T₁ - 1/T₂)

T is in Kelvin

H° is the enthalpy of the reaction and need to have the units J/mol due to the presence of the constant R.

R = 8.314 J/mol K

This video contains an example problem which uses this equation.
