Can you please help me with these three questions im confused on

If Keq=16, and the starting concentrations of Q and R are both 40M, then the equilibrlum concentration of Q is M and the equilibrium concentration of R is For the conversion of reactant A to product B, the change in enthalpy is 7.34kJmol1 and the change in entropy is 19.3JK1. mol 1. Above what temperature, in Kelvin, does the reaction become spentaneous? K. Calculate G0 for the reaction A+BC+D if [A]=9.5M,[B]=2.1M,[C]=3.4M, and the [D]=4.5M
