The lapse rate is 2ºC/1,000m = 0.6º/1,000ft  or 0.2ºC/100m.   This is less than the SALR (1.8ºC/1,000ft or 0.6/100m) the air is stable.

If the ELR is less than the SALR the airmass is stable. If it is more than the SALR but less than the DALR we have conditional stability and if it is more than the DALR it is unstable.
